Description

Perfluoroheptanoic acid (PFHpA) is a high-purity fluorinated organic compound with the molecular formula C₇HF₁₃O₂ and CAS number 375-85-9. This fully fluorinated carboxylic acid, also known as 2,2,3,3,4,4,5,5,6,6,7,7,7-tridecafluoroheptanoic acid, is characterized by its exceptional chemical stability, thermal resistance, and hydrophobic properties due to its perfluorinated carbon chain. It is supplied as a clear, colorless liquid with high purity (>98%) suitable for advanced research and industrial applications.

PFHpA is widely utilized in materials science, surface modification, and as a precursor for synthesizing fluorinated surfactants and polymers. Its unique properties make it valuable in coatings, electronics, and specialty chemical formulations where low surface energy and chemical inertness are critical. Proper handling is required due to its potential environmental persistence.

Application

Perfluoroheptanoic acid (PFHpA) is used as a surfactant or wetting agent in fluoropolymer production and firefighting foams. It serves as a key intermediate in synthesizing fluorinated compounds for hydrophobic coatings and stain-resistant materials. Researchers also employ PFHpA in environmental studies due to its persistence as a per- and polyfluoroalkyl substance (PFAS).
