Perfluorooctanesulfonyl fluoride (POSF) is a synthetic perfluorinated compound with a sulfonyl fluoride functional group. It is used to make perfluorooctanesulfonic acid (PFOS) and PFOS-based compounds. These compounds have a variety of industrial and consumer uses but POSF-derived substances ultimately degrade to form PFOS.Because of environmental concerns over PFOS 3M ceased POSF use in 2002 and global production plummeted. However Chinese production grew after 3M’s phaseout.
