CAS 335-67-1: Perfluorooctanoic acid

Description: Perfluorooctanoic acid (PFOA), with the CAS number 335-67-1, is a synthetic perfluoroalkyl substance (PFAS) characterized by a long carbon chain fully saturated with fluorine atoms, making it highly stable and resistant to degradation. It is a colorless, odorless liquid at room temperature and is soluble in organic solvents but insoluble in water. PFOA is known for its surfactant properties, which allow it to reduce surface tension, making it useful in various industrial applications, including the production of non-stick coatings, water-repellent fabrics, and firefighting foams. However, PFOA is also recognized for its persistence in the environment and potential health risks, including developmental and reproductive toxicity, as well as links to certain cancers. Due to these concerns, many countries have implemented regulations to limit its use and release into the environment. Its long half-life in human and animal bodies raises significant concerns regarding bioaccumulation and long-term exposure effects.
