Quats are ammonium salts. Each quat molecule has a central "core" characterized by a positively-charged nitrogen atom (N+) that is attached to other chemically-active groups that include carbon. Many different quat-based compounds are created by modifications of this basic molecule. The quats are used as sanitizers and disinfectants.
