Perfluorooctane sulfonate (PFOS, potassium salt) was purchased from Fluka Chemical (Steinheim, Switzerland). The chemical was reported to be 91% pure by the supplier. Our analysis indicated that approximately 71% of the chemical was straight-chain, and the remaining 29% was branched.

Nov 20, 2014 Reagents. Perfluorooctanesulfonic acid potassium salt (PFOS), Dimethylsulfoxide (DMSO), 3-(4,5-Dimethylthiazol-2-yl)-2,5

PFOS, together with PFOA , has also been used to make aqueous film forming foam (AFFF), a component of fire-fighting foams , and alcohol-type concentrate foams . The surface active properties of the potassium salt of PFOS make a direct determination of the octanol-water partition coefficient impossible. In a preliminary study reported by 3M an inseparable emulsion was formed. 3M determined the solubility of PFOS (K salt) in octanol as 56 mg/L, and calculated the log Kow from the ratio of solubilities, giving a log Kow value of -1.08.

Perfluorooctanesulfonic acid (PFOS), or perfluorooctane sulfonate, is a man-made fluorosurfactant and global pollutant. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009.[1] PFOS can form from the degradation of precursors in addition to industrial production.

Sufficient information exists to address hazard classification for all SIDS human health endpoints. for example the potassium salt of PFOS has a solubility in fresh water of 370 mg/L and of 25 mg/l in filtered sea water. Chemical Name: Perfluorooctane Sulfonate Synonym: PFOS CAS: 1763-23-1 (acid) 29081-56-9 (ammonium salt) 70225-14-8 (diethanolamine salt) 2795-39-3 (potassium salt) 29457-72-5 (lithium salt) Serum concentrations appear to be the best dose-metric for extrapolating to humans. At the present »> PFOS is a perfluoralkyl sulfonate that is commonly used as a simple salt (such as potassium, sodium or ammonium) or is incorporated into larger polymers (EFSA 2008; EPA 2009c).

Perfluorooctane sulfonate (PFOS) is an emerging persistent organic pollutant widely distributed in the environment, wildlife, and human. In our studies, as observed under the transmission electron microscope, PFOS increased autophagosome numbers in HepG2 cells. It was confirmed by elevated LC3-II levels in Western blot analysis.
