Description

Perfluorosuccinic acid (CAS No. 377-38-8) is a highly fluorinated derivative of succinic acid with the molecular formula C₄H₂F₄O₄. Its IUPAC name, 2,2,3,3-tetrafluorobutanedioic acid, reflects its fully substituted fluorine atoms on the carbon backbone. This compound is characterized by its strong acidity and unique reactivity due to the electron-withdrawing effects of the fluorine atoms. It is commonly used as a building block in the synthesis of fluorinated polymers, surfactants, and specialty chemicals. Perfluorosuccinic acid is supplied as a high-purity solid, ensuring consistency for research and industrial applications. Proper handling with PPE is recommended due to its corrosive nature.
