4057 2-(N-Ethyl-perfluorooctane sulfanamido) acetic acid 2-(N-Ethyl-perfluorooctane sulfanamido) acetic acid is a perfluoroalkyl acid (PFAA). PFAAs have been frequently detected in both the environment and in plants fish and animals. It is a metabolic breakdown product of Perfluorooctane sulfonate (PFOS) that can be detected in biofluids. PFOS has been used in a wide variety of industrial and consumer products including protective coatings for carpets and apparel, paper coatings, insecticide formulations, and surfactants. Like many PFAAs, it is persistent and bioaccumulative. PFAAs are thought to be endocrine disruptors. Many are known toxicants and carcinogens. 2991-50-6 18134 C12H8F17NO4S 585.24 White powder.
