Ammonium perfluorononanoate

Ammonium perfluorononanoate is a chemical compound that belongs to the class of per- and polyfluoroalkyl substances (PFAS). It is a salt formed from perfluorononanoic acid (PFNA), which has nine carbon atoms in its molecular structure, and ammonium. PFAS compounds are characterized by their strong carbon-fluorine bonds and their resistance to degradation, leading to concerns about their persistence in the environment and potential health effects.
