CAS 39108-34-4: 1H,1H,2H,2H-Perfluorodecanesulfonic acid
Description:1H,1H,2H,2H-Perfluorodecanesulfonic acid, commonly referred to as PFDSA, is a perfluorinated compound characterized by a long carbon chain with a sulfonic acid functional group. It is part of a larger class of substances known as per- and polyfluoroalkyl substances (PFAS), which are known for their water- and grease-repellent properties. PFDSA is highly stable due to the strong carbon-fluorine bonds, making it resistant to degradation in the environment. This stability, while beneficial for certain applications, raises concerns regarding its persistence and potential bioaccumulation in living organisms. The sulfonic acid group imparts acidic properties, allowing it to behave as a strong acid in aqueous solutions. PFDSA has been used in various industrial applications, including surfactants and coatings, but its environmental impact and potential health risks have led to increased scrutiny and regulation. As with many PFAS, there are ongoing studies to assess its toxicity and effects on human health and ecosystems.
