BACK TO MAIN WATER SOLUBILITY TEST SUBSTANCE Identity: Decafluoro(pentafluoroethyl)cyclohexanesulfonate, DEA salt; may be referred to as CS-2070. When dissolved in water may also be referred to or as CS-2151 or FC-90. (DEA salt of perfluoro(ethylcyclohexyl) sulfonate, [C2F5-CF(CF2CF2)2CFSO3-][H2N(CH2CH2OH)2+]) Remarks: The 3M production lot number is not applicable. The test sample is FC-90, a mixture of CS-2070 in water (approximately 25% test substance and 75% water). All values reported relate to the solids portion of this mixture (CS-2070). METHOD Method: Calculated GLP (Y/N): NA Year (study performed): 1982 Remarks field: Calculation was done using the distribution coefficient of CS-2070 (0.65) and the equation: log S = 6.5 - log Knw - 0.015 mp 0.89 The molecular weight of FC-90 (used to convert the results of the calculation from gmols/L to g/L) is 548. RESULTS___________________________________________________ Water solubility (S) = 250 g/L Remarks: Significant digits and rounding were not considered in this calculation. DATA QUALITY__________________________________________ Reliability: Klimisch ranking = 3. There is no information that validates this calculation for this compound. Additionally, the calculation is using a distribution coefficient rather than the octanol/water partition coefficient required for the calculation, and there is no information validating the distribution coefficient.
