CAS 375-92-8: Perfluoroheptanesulfonic acid

Description: Perfluoroheptanesulfonic acid (PFHSA), with the CAS number 375-92-8, is a perfluoroalkyl sulfonic acid characterized by a long carbon chain consisting of seven fully fluorinated carbon atoms, terminating in a sulfonic acid functional group. This compound is part of a larger class of per- and polyfluoroalkyl substances (PFAS), known for their unique properties, including high thermal stability and resistance to chemical degradation. PFHSA is highly hydrophobic and lipophobic, making it useful in various applications, such as surfactants, water-repellent coatings, and stain-resistant treatments. However, due to its persistence in the environment and potential health risks, including endocrine disruption and toxicity, PFHSA has raised significant environmental and regulatory concerns. Its bioaccumulation potential and long half-life in biological systems further contribute to its classification as a substance of concern. As a result, ongoing research is focused on understanding its behavior in the environment and its effects on human health.
