The perfluorooctanesulfonyl fluoride -based chemistry that was used to make sulfonamides like PFOSA was phased out by 3M in the United States (US) during 2000–2002 but it has grown in China by other producers. Perfluoroctansulfonsäure (Anion Perfluoroctansulfonat oder kurz PFOS) ist eine chemische Verbindung aus der Gruppe der per- und polyfluorierte Alkylverbindungen (PFAS). United States Office of Land and Emergency EPA 505-F-17-001 Environmental Protection Agency Management (5106P) November 2017 1 Technical Fact Sheet – 2021-04-14 · In 2000 several member countries agreed to informally work together to collect information on the environmental and human health hazards of perfluorooctane sulfonate (PFOS) to produce a hazard assessment. The decision followed the announcement by a major US manufacturer (3M) to globally phase out 1H,1H,2H,2H-PERFLUOROOCTANE SULFONATE (6:2 FTS), SODIUM SALT (13C2, 99%; D4, 98%) 50 UG/ML IN MEOH. * For isotopically labeled compounds, MW listed is for the fully enriched product.
