BACK TO MAIN SOLUBILITY IN PURE WATER, METHANOL, AND ACETONE - SHAKE FLASK METHOD TEST SUBSTANCE___________________________________________ Identity: Perfluorooctanoic acid, ammonium salt; may also be referred to as PFOA, PFOA ammonium salt, Ammonium perfluorooctanoate, FC-116, FC-126, FC-169, or FC-143. (Octanoic acid, pentadecafluoro-, ammonium salt, CAS # 3825-26-1 ) Remarks: Sample is a white powder. The 3M production lot number was 332. The 3M Test, Control, Reference number is TCR-99131-037. It's purity was characterized, and an Interim Certificate of Analysis issued indicating it contains 95.2% test substance. METHOD__________________________________________________ Method: Based on OECD 105, OPPTS 830.7840. GLP (Y/N): Yes Year completed: 2001 Solvent Sources: Pure water = ASTM Type I water, Millipore Methanol = B & J Brand, HPLC Grade Acetone = EM Science, HPLC Grade Remarks: The screening test consisted of placing approximately 10 mg PFOA into a glass vial, and adding 0.1 mL of the appropriate solvent. The vial was shaken, sonicated, and observed for particulates. RESULTS___________________________________________________ ASTM Type I Water: Methanol: Acetone: >10% (w/v) at 23C >10% (w/v) at 23C >10% (w/v) at 23C Description of solubility: Highly soluble. Remarks: Per the test method, once solubility was established as >10%, no further testing was required. Definitive studies were therefore not conducted. BACK TO MAIN CONCLUSIONS_____________________________________________ The solubility concentration of the test substance in pure water, methanol, and acetone was >10% (w/v) for each respectively.
