Application

Heptadecafluorooctanesulfonic acid solution can be used as a catalyst:
  • In the benzoylation of a variety of unactivated benzenes via Friedel-Crafts acylation reaction in the presence of rare earth(III) perfluorooctane sulfonate in fluorous solvents.
  • For the dinitration of aromatic compounds to synthesize dinitrobenzenes in the presence of ytterbium perfluorooctane sulfonate and fluorous solvent.
  • To synthesize tetrahydroisoquinoline derivatives via Pictet-Spengler reaction of β-arylethyl carbamates with aldehydes.

The formation of perfluorinated surfactants (PFSs) from their precursors in waters is of concern. In this study, the formation of PFSs through biodegradation of precursors was measured in incubation tests. Indigenous microorganisms in groundwater were able to biodegrade perfluorooctane sulfonamide

A method was developed for simultaneous analysis of perfluoroalkane sulfonic acids (PFSAs) and their sulfonamide-based precursors (perfluoroalkane sulfonamidoacetic acids (FASAAs), sulfonamides (FASAs), and sulfonamidoethanols (FASEs)) in fish muscle. Extraction was performed with acetonitrile followed by a clean-up and fractionation step
