CAS 375-85-9: Perfluoroheptanoic acid

Description: Perfluoroheptanoic acid (PFHA), with the CAS number 375-85-9, is a perfluorinated carboxylic acid characterized by a seven-carbon chain fully saturated with fluorine atoms, making it highly hydrophobic and lipophobic. This unique structure imparts exceptional thermal and chemical stability, as well as resistance to degradation in the environment. PFHA is known for its surfactant properties, which allow it to reduce surface tension and enhance the spreadability of formulations. It is often used in various industrial applications, including the production of fluoropolymers and as a processing aid in the manufacture of water- and oil-repellent coatings. However, due to its persistence in the environment and potential health concerns, including bioaccumulation and toxicity, PFHA has come under scrutiny and regulatory review. Its behavior in biological systems and the environment is a subject of ongoing research, particularly regarding its long-term effects on human health and ecosystems. Overall, PFHA exemplifies the challenges associated with the use of perfluorinated compounds in modern chemistry and industry.
