PURPOSE AND PRINCIPLE
The purpose of the study was to determine the partition coefficient of the test substance between n-octanol and water.
The partition coefficient(n-actanollwater)(POW) is defined as the ratio of the equilibrium concentrations in a two phase system consisting of n-octanol and water.
The retention time of a substance in a reversed-phase High Performance liquid Chromatography (HPLC) chromatographic system is related to its partitioncoefficient(n-octanol/water). The HPLC method is useful for log Pow values between 0 and 6. Using the HPLC method, impurities are of minor importance. The HPLC method must also be applied if the test substance is a mixture of compounds but is not applicable to strong acids and bases, metal complexes, substances which react with the eluent or surface-active agents.
GUIDELINES
The study procedure described in this report was based on the following guidelines:
Organization for Economic Co-operation and Development (OECD), OECD Guideline for Testing of Chemicals..guideline no. 117: NPartition coefficient (n-octanol/water) High Performance Liquid Chromatography (HPLC) methodu (adopted March 30, 1989).
European Economic Community (EEC), EEC-Directive 92/69 EEC, Annex V, Part A, Methods for the determination of physica-chemical properties, A.8: 'Partition coefficientu. EEC Publication no. L383, December 1992.
ARCHIVING

TEST SYSTEM AND RATIONALE
A High Performance Liquid Chromatograph with a spectrophotometric detector. The stationaryphase was bonded silica C18. The mobile phase was 75/25 (v/v)acetonitrile/waterB.oth HPLC instrumentatioannd conditionsare describedin the section "methodof chemicalanalysism.
The test systemwas recognizedby the internationalguidelines(OECD, EEC).
REFERENCE SUBSTANCES

consistedof:

PERFORMANCEOF THE TEST
Preparationof the solutions
Solutionsof the referencesubstanceswere prepared in methanol (HPLC-grade, LabscanLimitedCo., Dublin,Ireland)at a concentrationof 1.5-2g/l. A mixture of the referencesubstanceswas preparedby adding125 ul of each solutionto a volumetricflask.Subsequently,this flaskwas made up with mobilephase to a final volumeof 25.0 ml. For the determinationof.to (retentiontime of the unretardedcomponent),a solutionof formamide(p a., Merck, Darmstadt,FRG) in methanolwas prepared at a concentrationof 1.7 g/l and thereafterdiluted10 timeswith mobile
phase. A stock solution of T-5869 was preparedby dissolving287 mg test substance in 50.0 ml acetonitrile(2 minutes sonication).The stock solutionwas diluted10 times with mobi.lephase,resultingin the test solution.

Performance of the test
The solutions were injected in the following sequence: the mixture of reference substances, mobile phase, the formamide solution, the test solution (in duplicate), mobile phase, the mixture of referencesubstances and the formamide solution.
Temperature of measurement
The temperature of the mobile phase was recorded several times during the measurements.

DATA HANDLING
Using High Performance Liquid Chromatography, especially large log Pow values can be accurately determined,from the chromatographicretention a a. To this end, the capacity factor (k ) was used, since it is proportionalto the partition coefficient. The capacity factor was calculatedfrom the retention of the substance concerned (tr) and the unretardedcomponent (to):
k' = (tr- to)/to
From the results of the reference substances,a plot of log Pow (x-value) versus log k' (y-value) was constructed, using linear regressionanalysis. The log k value of each component of the test substance was compared with the log k' values of the reference substances with known log Pow values.

NOTOX Project 121286
RESULTS
Representative HPLC chromatograms of the test solution, the blank (mobile phase), the mixture of reference substances and the formamide solution are shown in Figures 1 to 4.
In the HPLC chromatograms of T-5869, using detection at 210 nm, one large and 2 small test*substance peaks were observed. In addition, many small test substance peaks were observed between approximately 1 and 6 minutes. It was assumed that the large peak derived from the major component of test substance whereas the small peaks derived from impurities.
The to was determined to be 0.90 minutes as a mean value,of both measurements (i.e 0.89 and 0.90 minutes).
The mean values of the retention times, k' values, log k' values, log P w and Pow values are summarized In Table 1. The plot of log Pow (x-va?ue) versus log k' (y-value) from the reference substances is shown in Figure 5.
