CAS 375-22-4: Heptafluorobutyric acid

Description: Heptafluorobutyric acid, with the CAS number 375-22-4, is a perfluorinated carboxylic acid characterized by the presence of seven fluorine atoms attached to a four-carbon butyric acid backbone. This compound is notable for its high stability and low reactivity due to the strong carbon-fluorine bonds, which make it resistant to degradation. Heptafluorobutyric acid is a colorless liquid at room temperature and has a high boiling point compared to its non-fluorinated counterparts. It is soluble in organic solvents but has limited solubility in water. The presence of the carboxylic acid functional group imparts acidic properties, allowing it to participate in various chemical reactions, including esterification and salt formation. Due to its unique properties, heptafluorobutyric acid is used in specialized applications, such as in the synthesis of fluorinated compounds and as a reagent in analytical chemistry. However, its environmental impact and potential toxicity are considerations in its handling and use.
