Perfluoroheptanoic acid (CAT: R059260) is a fully fluorinated carboxylic acid with the molecular formula C₇HF₁₃O₂, belonging to the class of per- and polyfluoroalkyl substances (PFAS). It is a colorless to white solid or viscous liquid known for its exceptional chemical stability, hydrophobicity, and lipophobicity due to the strong carbon–fluorine bonds. PFHpA is used in research and industry as a surfactant, processing aid in fluoropolymer manufacturing, and performance additive in specialty coatings, textiles, and firefighting foams. In environmental and toxicological studies, it serves as a model compound for understanding PFAS persistence, bioaccumulation, and potential health effects, as it resists degradation under typical environmental conditions.
