WATER SOLUBILITY TEST SUBSTANCE Identity: N-ethylperfluorooctane sulfonamidoethanol; may also be referred to as. N-EtFOSE Alcohol or FM-3422. (1-Octanesulfonamide, N-ethyl1.1,22,3,3,4,4,5,5,6,6,7.7.8,8,8-heptadecafluoro-N-(2-hydroxyethyl)-, CAS #1691992) Remarks: Material is an off-white, waxy solidof uncharacterized purity. METHOD: Method followed: The Veith-Comstock technique, G. D. Veith and V. M. Comstock, J. Fish Res. Board Can., 32, 1849 (1975) GLP: No Year study was performed: 1977 Remarks: This experiment was performed 8 times. No information is given on sample purity. RESULTS Value (mg/L) at20 C: Mean value = 0.05 (0.04-0.062 Range over 8 trials) CONCLUSIONS The test substance has solubility in the mid part per billion range. DATA QUALITY Reliability: Kiimisch ranking = 3. tis useful in that it indicates the approximate N-EtFOSE alcohol water solubility. The test water was not sufficiently characterized, nor was the purity of the test material noted. Testing will be redone using current methods and analytical techniques. Testing will be conducted using a purified sample. REFERENCES 3M Technical Report Summary, Fateof Fluorochemicals, 3M Environmental Laboratory, 3M Environmental Engineering and Pollution Control, A.

LETERMINATION OF SOLUBILITY OF FM 3422 IN WATER The Veith-Comstock technique (2) was used for this experiment. Glass beads (ca. 300 g, 3 mm. in diameter) were added to a solution of e1v0a0ponrgatoef,FMthu4s22depionsiabtoiuntg t5h0e0 mflluoOrfocacheetmoincea.l onThethesoblevaednst.waTshealbleoawdesd wteore Wpiatchkeda 20inmto, alcayoelrumof(scai.lan25izemmd. gldiaas.s wxoo4l5,0 mfmo.l)lowwheodsebyenad2w0asmm.prelpaaycekredof sand.
