1H,1H,2H,2H-Perfluorooctanesulfonic acid

Description:
1H,1H,2H,2H-Perfluorooctanesulfonic acid (PFOS) is a synthetic perfluoroalkyl substance (PFAS) characterized by a long carbon chain fully fluorinated, which contributes to its unique chemical properties. It features a sulfonic acid functional group, making it highly soluble in water and resistant to degradation. PFOS is known for its surfactant properties, allowing it to reduce surface tension and enhance the spreadability of liquids, which has led to its use in various applications, including stain repellents, firefighting foams, and industrial processes. However, PFOS is persistent in the environment and bioaccumulates in living organisms, raising significant environmental and health concerns. Studies have linked PFOS exposure to various adverse health effects, prompting regulatory actions in many countries to limit its use and presence in consumer products. Its persistence and potential toxicity have led to increased scrutiny and research into safer alternatives within the broader category of PFAS compounds.
