    Trifluoroacetic acid, a moderately strong acid useful in organic chemistry. Heptafluorobutyric acid, a moderately strong acid that is useful in organic and analytical chemistry. Pentafluorobenzoic acid, a moderately strong acid of interest in research community. Perfluorooctanoic acid (PFOA),a surfactant used to make fluoropolymers such as Teflon.

  4. Perfluoroalkyl carboxylic acids - Wikipedia

    en.wikipedia.org/wiki/Perfluoroalkyl_carboxylic...

    Trifluoroacetic acid is a widely employed acid, used for example in the synthesis of peptides.Its esters are useful in analytical chemistry. Longer-chain perfluoroalkyl carboxylic acids, e.g. with five to nine carbons, are useful fluorosurfactants and emulsifiers used in the production of polytetrafluoroethylene (Teflon) and related fluoropolymers.
