Perfluorodecanesulfonic acid

Description:
Perfluorodecanesulfonic acid (PFDSA) is a perfluorinated compound characterized by a long carbon chain with a sulfonic acid functional group. It belongs to a class of substances known as per- and polyfluoroalkyl substances (PFAS), which are known for their unique properties, including high thermal stability and resistance to water, oil, and grease. PFDSA is typically a colorless to pale yellow liquid or solid, depending on its form and temperature. Its molecular structure imparts significant hydrophobic and lipophobic characteristics, making it useful in various industrial applications, such as surfactants and coatings. However, like other PFAS, PFDSA is persistent in the environment and has raised concerns regarding its potential health effects, including bioaccumulation and toxicity. Regulatory scrutiny has increased due to its environmental persistence and potential impacts on human health, leading to ongoing research into its behavior in ecosystems and the development of safer alternatives.
