It is a fluorocarbon derivative and a perfluorinated compound, having an eight-carbon chain and a terminal sulfonamide functional group. Perfluorooctane sulfonate (PFOS) and Its Salts and Transformation and Degradation Precursors Perfluorooctane sulfonate (PFOS) and its salts are perfluorinated organic compounds with surfactant properties. Common salts of PFOS include the ammonium, diethanolamine, potassium, and lithium forms. PFOS can be Cambridge Isotope Laboratories offers 1H,1H,2H,2H-PERFLUOROOCTANE SULFONATE (6:2 FTS), SODIUM SALT (13C2, 99%; D4, 98%) 50 UG/ML IN MEOH for all your research needs.

PFOS exhibits similar properties and, like PFOA, has been used in a variety of consumer products (e.g., Scotchgard) for its stain-, grease- and water-resistant properties. Emerging evidence suggests associations between Perfluoroalkyl substances (PFASs) exposure and asthma, but the findings are inconsistent.

Perfluorooctanesulfonic acid is an anthropogenic fluorosurfactant and global pollutant. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009. PFOS can be synthesized in industrial production or result from the degradation of precursors. PFOS levels that have been detected in wildlife are considered high enough to affect health parameters, and recent PFOS is part of a class of chemicals called per- and polyfluoroalkyl substances (PFASs).

Item Number. CLM-8505-1.2. Chemical Formula. *C8F17NaO3S.

These compounds degrade to perfluorooctanesulfonate (PFOS) which is regarded as a persistent end-stage metabolite and is found to accumulate in tissues of humans and wildlife. Perfluorooctane sulfonic acid (PFOS) is mainly used in the form of its salts (ammonium, potassium and lithium salts, among others) in the water and grease repellent impregnation of textiles, carpets and paper, in addition to chrome plating, in various photolithographic chemicals and in hydraulic fluids for aviation.
