Sulfluramid (N-EtFOSA) is a chemical compound from the group of sulfonic acid amides and per- and polyfluoroalkyl substances (PFASs) that is effective as an insecticide.
Annual production increased from about 30 tons in 2003 to 60 tons in 2013.[1]
Environmental issues
It is predominantly biotransformed to perfluorooctanesulfonic acid (PFOS),[2] but partly also to perfluorooctanoic acid (PFOA).[3][4] Sulfluramid benefits from an acceptable purpose in the listing of PFOS to annex B of the Stockholm Convention on Persistent Organic Pollutants.
