Preparation of Perfluorooctanesulfonic acid amide: It can be obtained from perfluorooctanesulfonyl halides by reaction with liquid ammonia or by a two step reaction via an azide followed by reduction with Zn/HCl.

Uses of Perfluorooctanesulfonic acid amide: It is used in the synthesis of fluorine surface active agent, introducting other groups to the nitrogen atom. It is also thought to be the biologically active form of the insecticide Sulfluramid (N-ethyl perfluorooctanesulfomamide) as it is an extremely potent uncoupler of oxidative phosphorylation with an IC50 of about 1 micromolar.
