Heptafluoro-1-butanoic acid; Heptafluorobutanoic acid; Heptafluorobutyric acid; Kyselina heptafluormaselna [Czech]; Perfluorobutanoic acid; Perfluoropropanecarboxylic acid; Butanoic acid, 2,2,3,3,4,4,4-heptafluoro-; Butanoic acid, heptafluoro-; Butyric acid, heptafluoro-; [ChemIDplus] UN3265
Colorless liquid with an unpleasant odor; [MSDSonline]
Perfluorocarboxylic acids include Perfluoroacetic, Perfluoropropionic, Perfluorobutyric, Perfluorovaleric, Perfluorocaproic, Perfluoroheptanoic, Perfluorocaprylic, Perfluorononanoic, Perfluorocapric, Perfluoroundecanoic, and Perfluorododecanoic acid; These long-chain perfluoroalkanecarboxylic acids and their salts are used as wetting, dispersing, emulsifying, and foaming agents. They greatly reduce surface tension in aqueous solutions. [Ullmann]
