Perfluorobutyl

Perfluorobutyl refers to a four-carbon alkyl group where all hydrogen atoms have been replaced by fluorine atoms. Its chemical formula is C4F9. This highly fluorinated group is a component of various per- and polyfluoroalkyl substances (PFAS). The strong carbon-fluorine bonds in the perfluorobutyl group contribute to the stability and persistence of these compounds in the environment. Due to this stability, PFAS containing perfluorobutyl moieties have been used in a wide range of industrial and consumer products, including firefighting foams, non-stick coatings, and stain-repellent treatments. However, the environmental persistence and potential health concerns associated with PFAS have led to increased scrutiny and regulation of these substances. Research into the environmental fate and toxicological effects of perfluorobutyl-containing compounds is ongoing, with a focus on understanding their behavior in ecosystems and their impact on human health. Efforts are also underway to develop alternative chemistries that can replace PFAS in various applications.
