What is Perfluorohexanoic acid?

Chemical properties

Perfluorohexanoic acid (PFHxA) exists as a colourless liquid, it is insoluble in water. Perfluorohexanoic acid has the ability to react with strong oxidizing agents. Upon decomposition, PFHxA can form carbon oxides and hydrogen fluoride. Additional information related to the physical and chemical properties of PFHxA are not currently available.

The Uses of Perfluorohexanoic acid

Perfluorohexanoic acid (PFHxA, perfluorocaproic acid, undecafluorohexanoic acid, undecafluoro-1-hexanoic Acid) is a six-carbon compound in the perfluoroalkyl family of chemicals. Perfluorohexanoic acid is used in stain- and grease-proof coatings on furniture, carpet, and food packaging. Perfluorohexanoic acid is the six-carbon version of the highly persistent and outlawed PFOA. Much like other perfluoroalkyls, PFHxA can persist in the environment.

The Uses of Perfluorohexanoic acid

Undecafluorohexanoic acid, a volatile ion-pair reagent, has been used as mobile phase for LC-MS analysis of highly polar sulfonium pseudo-sugar constituents neosalacinol and neokotalanol, potential α-glucosidase inhibitors isolated from ayurvedic traditional medicine Salacia species.
