Nonafluoropentanoic acid (CAT: R026963) is a fully fluorinated carboxylic acid widely recognized for its exceptional chemical and thermal stability. With the molecular formula C₄F₉COOH, it functions as a critical surfactant and processing aid in the manufacture of high-performance fluoropolymers, including PTFE. Its strong hydrophobic and lipophobic nature makes it ideal for use in specialty coatings, emulsions, and surface treatments. Additionally, NFPA is extensively studied in environmental science as a representative perfluoroalkyl substance (PFAS) due to its persistence, potential bioaccumulation, and toxicological impact.
