Six groups of 5 male Crl:CD(SD)IGSBR rats each were given 100 mg/kg/day of H-24043. The test substance was administered to one group of 5 rats for 5 consecutive days and to 5 groups for 10 days. Approximately 2 hours after the first dose, blood was collected from the orbital sinus of each rat from the 5-dose group. On selected days (5, 10,13,24, 51/52, 94) 5 rats per group were euthanized and the blood and livers were collected. Body weights and clinical signs were recorded on each day of dosing and then approximately every other week during the recovery period. Additionally, 3 negative controls, deionized water, corn oil, and corn oil/acetone (80:20), and 2 positive controls, H-24019 (10 mg/kg/day) and H-24020 (20 mg/kg/day), were tested as described for H-24043. No deaths occurred during the study. No compound-related clinical signs oftoxicity were observed in the rats dosed with the test substance, H-24043. Rats dosed with H-24019 exhibited diarrhea, salivation, alopecia, black ocular discharge, and staining of various parts of the body during the dosing period. Rats dosed with H-24020 exhibited wet perineum and diarrhea during the dosing period. Alopecia was observed during the recovery period in rats dosed with deionized water and the positive controls, H-24019 and H-24020. The corn oil and corn oil/acetone negative control rats exhibited no clinical signs during the study. The mean body weights and mean body weight gains of the rats dosed with H-24043 were comparable to the deionized water and corn oil negative controls and higher than the H-24020 positive controls. Comparison of body weights between the rats dosed with H-24043 and the corn oil/acetone negative control and H-24019 positive control rats was complicated by the fact that there was a difference in age on test day 1 between the rats. Accounting for the age difference at study start and the expected rate of body weight gain, it appears that the mean body weights and mean body weight gains of the rats dosed with H-24043 is comparable to the corn oil/acetone negative controls and equal to or greater than the H-24019 positive controls. A steady-state for fluorine levels in whole blood was not achieved during 10 consecutive days of dosing with 100 mg/kg H-24043. An area under the curve (estimated to infinity) was calculated and normalized for fluorine content for the test substance and each positive control. The AUCINF/D for the fluorine component of H-24043 was 23,298.6 as compared to AUCINF/D values of 566,479.1 and 70,789.6 for H-24019 and H-24020, respectively. Under the conditions of this study, administration of the test substance, H-24043, to male rats for 10 consecutive days resulted in moderate absorption and retention of fluorine in the blood. Dose-adjusted areas under the curve (AUCINF/D) for positive controls, H-24019 and H-24020, were approximately 25x and 3x the AUCINF/D for the test substance. 8- 9 H-24043: Biopersistence Screening 10-DoseOral Gavage Study in Rats DuPont-2932 INTRODUCTION The objective of this study was to define the potential of H-24043 to be absorbed and to bioaccumulate in a mammalian system, as indicated by analytical determination of total fluorine in blood and liver. The test substance was compared to 2 positive controls that were materials previously shown to bioaccumulate in mammals. The initial dosage chosen for the study was 500 mg/kg/day. However, dosing was terminated after 5 days. The mean body weight of the rats after 5 days of dosing was decreased by 7% compared to the mean body weight on the first day of dosing. The dosage of 500 mg/kg/day was chosen based on the results ofrangefinding studies. In the first rangefinding study, 5 rats were dosed with the test substance for 5 consecutive days at a daily dosage of 300 mg/kg. The rats dosed with H-24043 experienced an overall mean body weight gain of 29 grams. The control group also had an overall mean body weight gain of 29 grams. In the second rangefinding study, 5 rats were dosed with H-24043 for 5 consecutive days at a daily dosage of 750 mg/kg. These rats had an overall mean body weight loss of 19 grams. The dosage of 100 mg/kg/day was chosen based on the results of 2 additional rangefinding studies. The dosage of 300 mg/kg/day was repeated. Five rats dosed with H-24043 for 5 consecutive days at a dosage of 300 mg/kg/day had an overall mean body weight gain of 6 grams. Five rats were also dosed with H-24043 for 5 consecutive days at a dosage of 100 mg/kg/day. These rats experienced an overall body weight gain of 16 grams. The control group had an overall mean body weight gain of 25 grams. All blood samples were analyzed for total fluorine content. This report contains the results of those analyses. Results from analyses of selected liver samples will be presented in a supplemental report. MATERIALS AND METHODS A. Test Substance and Positive Control The test substance, H-24043, was supplied by the sponsor as a light amber brown liquid. The positive controls, H-24019 and H-24020, were supplied by the sponsor as white solids. The test substance and positive controls appeared to be stable under the conditions of the study. No evidence of instability, such as a change in color or physical state, was observed. B. Test Species Male Crl:CD(SD)IGS BR rats were received from Charles River Laboratories, me., Raleigh, North Carolina. The Crl:CD(SD)IGSBR rat was selected on the basis of extensive experience Company Sanitized.

Animal Husbandry 1. Housing Environment Rats were housed singly in stainless steel, wire-mesh cages suspended above cage boards. Animal rooms were maintained on an approximate 12-hour light/dark cycle (fluorescent light) and at a temperature of 23 1C and a relative humidity of 50 10%. Occasional excursions outside the accepted ranges were minor and did not affect the study. 2. Feed and Water Tap water was provided ad libitum. All rats were fed PMI Nutrition International, Inc. Certified Rodent LabDiet 5002 chow. The feed is guaranteed by the manufacturer to meet specified nutritional requirements and to be free of specified contaminants. 3. Identification Prior to assignment to groups, each rat was temporarily identified by cage identification. After assignment to groups, an individual identification number was marked or tattooed on the tail of each rat. The information on the cage labels included the unique 6-digit Haskell animal number assigned to each rat. 4. Animal Health Monitoring Program As specified in the Haskell Laboratory animal health and environmental monitoring program, the following procedures are performed periodically to assure that contaminant levels are below those that would be expected to impact the scientific integrity of the study: Water samples are analyzed for total bacterial counts, and the presence ofcoliforms, lead, and other contaminants. Feed samples are analyzed for total bacterial, spore and fungal counts. Samples from freshly washed cages and cage racks are analyzed to ensure adequate sanitation by the cagewashers. Certified animal feed is used, guaranteed by the manufacturer to meet specified nutritional requirements and not to exceed stated maximum concentrations of key contaminants, including specified heavy metals, aflatoxin, chlorinated hydrocarbons, and organophosphates. The presence of these contaminants below the maximum concentration stated by the manufacturer would not be expected to impact the integrity of the study. The animal health and environmental monitoring program is administered by the attending laboratory animal veterinarian. Company Sanitized.

Quarantine and Pretest Upon arrival at Haskell Laboratory, the rats were removed from shipping cartons and quarantined for 6 days. The rats were weighed 3 times during the pretest period and examined daily for any clinically apparent signs of disease or injury. The rats were observed daily for mortality and signs of illness, injury, or abnormal behavior. On the bases of acceptable body weight gains and freedom from clinically apparent signs of disease or injury, the rats were released from quarantine by the laboratory animal veterinarian designee. E.

Assignment to Groups and Study Start After the quarantine period, the rats were selected on the bases of adequate body weight gain, freedom from any clinical signs of disease or injury, and a body weight within 20% of the mean. The selected rats were divided by computerized, stratified randomization into 6 groups of 5 rats, so that there were no statistically significant differences among group body weight means. After assignment to groups, each rat was housed individually. The last 3 digits of the animal number was marked or tattooed on the tail of each rat. The rats were between 7 and 9 weeks of age at the time of dosing. Dosing began on test day 1. Rats that were not assigned to the study were released for other laboratory purposes, or were sacrificed by carbon dioxide asphyxiation and discarded without pathological evaluation. G. Dosing Material Preparation and Administration 1. Test Substance H-24043 was mixed with deionized water so an accurate volume could be delivered. The amount of test substance each rat received was based on the body weight collected on each day of dosing and the dosing mixture concentration. The rats were dosed at a volume of 1 mL/100 g of Company Sa.-rf.-ed. Doe- "<- ''-mfa;n TSCA C81 -11 - H-24043: Biopersistence Screening 10-Dose Oral Gavage Study m Rats DuPont-2932 body weight. The dosing mixture was stirred on a magnetic stir plate throughout the dosing procedure to maintain homogeneity. 2. Positive Controls The solid positive control compounds were suspended as emulsions in their respective vehicles. Corn oil was used as the vehicle for H-24019. It was necessary to dissolve H-24020 in acetone before suspending it in corn oil. The ratio of acetone to corn oil was 20:80. The amount each rat received was based on the body weight collected on each day of dosing and the suspension concentration. The dose volumes did not exceed 1 mL/100 g of body weight. The dosing suspensions were stirred on a magnetic stir plate throughout the dosing procedure to maintain homogeneity. 3. Negative Controls Deionized water was chosen as a negative control because it was the vehicle for the test substance. Corn oil and corn oil:acetone (80:20) were chosen as negative controls because they were the vehicles for the positive controls. Each negative control rat received 1 mL of corn oil or corn oil:acetone. These rats were dosed in a separate room from the rats dosed with the test substance or positive controls. H. Body Weights All rats were weighed on each day of dosing. The rats were weighed weekly or every other week during the recovery period. I. Mortality and Clinical Observations Cage-site examinations to detect moribund or dead rats and abnormal behavior and appearance among rats were conducted at least once daily throughout the study. At every weighing, each rat was individually handled and examined for abnormal behavior and appearance. J. Collection and Analysis of Blood and Livers Approximately 2 hours after the first dose, 1-2 mL of blood was collected into EDTA tubes from the orbital sinus of each rat from Group I. At all other selected time points, 5 rats/group were euthanized by carbon dioxide anesthesia and exsanguination, and the blood and livers were collected according to the following schedules: Company Sanitized.

The livers were weighed. The blood from all rats was refrigerated and the livers were frozen. The blood was appropriately packaged and shipped refrigerated to Jackson Laboratory, Deepwater, New Jersey where it was analyzed for total fluorine. The total fluorine content of the blood samples was determined using a Wickbold torch combustion method, followed by analysis with a fluoride ion selective electrode. The liquid blood was decomposed or volatilized in the presence of wet oxygen and swept through an oxyhydrogen flame in a closed quartz apparatus. The combustion products were collected in an aqueous absorbing solution and analyzed using a fluoride ion selective electrode. The analytical data (ppm F in each sample) was supplied to Haskell Laboratory personnel for evaluation of fluorine biopersistence. K. Treatment of Fluorine Data Noncompartmental analysis was conducted on blood fluorine data derived from rats dosed with H-24043 by using WinNonlin Version 3.0 software (Pharsight Corp. Mountain View, CA). WinNonlin software provided a means of computing derived pharmacokinetic parameters from data files including area under the curve (AUCINF), Cmax and terminal half-life (Ti/z). The AUCINF (concentration x time) represents the area under the blood concentration curve from the time of dosing extrapolated to infinity. The maximum observed concentration was Cmax (concentration). The points included in determination of the terminal half-life were selected manually and given in units of time. Since the dosages and fluorine content for each positive control and the test material varied, all doses were normalized to 0.1 mmole/kg for comparative purposes. The accumulation index (AL l^l-e'"")) and bioaccumulation index (BI, Cmax x Al) were calculated and reported but not further used. H-24019 and H-24020 were used as positive controls. Dosing diluents were used as negative controls, but because of variability and limited sensitivity of the analytical method, the background was set at 0.2 ppm fluorine. Since 0.2 ppm was the fluoride concentration limit of detection, any values listed as less than 0.2 ppm were excluded from further treatment. The percent of fluorine and molecular weight of the test substance and positive controls were used as provided by the sponsor. The measurements resulting from analysis of total blood fluorine were used as received (ppm F) from Jackson Laboratory. Fluoride ion was converted to Company Sanitized.

The data and descriptions of data manipulation and presentation are provided in Appendix C. RESULTS AND DISCUSSION A. In-Life Toxicology (Tables 1-2, Figure 1, Appendices A-B) No deaths occurred during the study. No compound-related clinical signs oftoxicity were observed in the rats dosed with the test substance, H-24043. Rats dosed with H-24019 exhibited diarrhea, salivation, alopecia, black ocular discharge, and staining of various parts of the body during the dosing period. Rats dosed with H-24020 exhibited wet perineum and diarrhea during the dosing period. One rat dosed with H-24043 exhibited alopecia and another exhibited a sore during the recovery period. Alopecia was observed during the recovery period in rats dosed with deionized water and the positive controls, H-24019 and H-24020. The corn oil and corn oil/acetone negative control rats exhibited no clinical signs during the study. The mean body weights and mean body weight gains of the rats dosed with H-24043 were comparable to the deionized water and corn oil negative controls and higher than the H-24020 positive controls. Comparison of body weights between the rats dosed with H-24043 and the corn oil/acetone negative control and H-24019 positive control rats was complicated by the fact that there was a difference in age on test day 1 between the rats. This difference resulted in differences in mean body weights on test day 1. The H-24043 rats were younger and lighter in weight than the corn oil/acetone negative control and H-24019 positive control rats. Younger animals experience a period of rapid body weight gain. Older animals are expected to gain weight at a slower rate than younger animals. Accounting for the age difference at study start and the expected rate of body weight gain, it appears that the mean body weights and mean body weight gains of the rats dosed with H-24043 is comparable to the corn oil/acetone negative controls and equal to or greater than the H-24019 positive controls. B. Fluorine Data (Tables 3-4, Figures 2-3, Appendix C) 1. Factors Influencing Interpretation of Analysis The data used in the kinetic analysis were derived from a limited screen, and therefore several caveats and considerations are important. A couple of considerations of particular importance are (1) a single dose was used and kinetics may or may not be linear, (2) the kinetics apply only to blood, (3) steady-state may not have been achieved, and (4) the sample size is low and may impact calculation of the terminal half-life. A more complete list of considerations is shown in Appendix C. Company Sanitized. Does not contain TSCA CBI -14- H-24043: Biopersistence Screening 10-Dose Oral Gavage Study in Rats DuPont-2932 2. Positive Controls The positive controls were H-24019 and H-24020. The H-24019 normalized yM equivalents in rat blood continued to rise throughout the dosing period and may not have reached steady-state (Figure 2A). The Cmax for H-24019 was 989.85 116.90 ppm (Mean, SD) with a terminal half-life of 40.5 days. The H-24019 AI was 59.0 and the BI was 58382.2. The H-24020 normalized fiM equivalents in rat blood peaked after 5 days of dosing and then decreased throughout the dosing period (Figure 2B). The Cmax for H-24020 was 518.12 44.89 ppm (Mean SD) with a terminal half-life of 8.3 days. The H-24020 AI was 12.5 and the BI was 6497.5. For each of the positive controls, blood was sampled at seven time points throughout the study, with only four of them occurring post-dose. The small sample size and analytical variability should be taken into account when using the derived terminal half-life for comparative purposes. The total internal exposure resulting from a normalized dose was described by AUCINF/D and was the basis for comparison between positive controls and the test material. The AUCINF/D for the fluorine component was 566,479.1 for H-24019 and 70,789.6 for H-24020. 3. Test Substance The H-24043 normalized ^iM equivalents in rat blood continued to rise throughout the dosing period and may not have reached steady-state (Figure 2C). The Cmax for H-24043 was 101.07 15.31 ppm (Mean SD) with a terminal half-life of 26.3 days. Blood was sampled at seven time points throughout the study, with only four of them occurring post-dose. The small sample size and analytical variability should be taken into account when using the derived terminal half- life for comparative purposes. The H-24043 AI was 38.4 and the BI was 3879.1. The total internal exposure resulting from a normalized dose was described by AUCINF/D and was the basis for comparison between H-24043 and positive controls. The AUCINF/D for the fluorine component of H-24043 was 23,298.6 as compared to AUCINF/D values of 566,479.1 and 70,789.6 for H-24019 and H-24020, respectively. The data, calculations and equations are shown in Appendix C. CONCLUSIONS Rats dosed for 10 consecutive days with the test substance, H-24043, exhibited no mortality or test substance-related clinical signs oftoxicity and had mean body weights and mean body weight gains that were comparable to the negative control rats. A steady state for fluorine in the blood was not achieved for H-24043 during the 10-day dosing period. Under the conditions of this study, administration of H-24043 to male rats for 10 consecutive days resulted in moderate absorption and retention of fluorine in the blood. Dose-adjusted areas under the curve (AUCINF/D) for positive controls, H-24019 and H-24020, were approximately 25x and 3x the AUCINF/D for the test substance.
