Definition: A "quaternary ammonium compound" (often shortened to "quats") is a type of chemical substance. It is made from a basic compound called ammonium, where some of the hydrogen atoms have been replaced by organic groups (parts of molecules containing carbon). These compounds are known for their ability to act as disinfectants (cleaning agents that kill germs), surface-active agents (which help substances mix together), and can also be found in certain medicines.
You would typically use the term "quaternary ammonium compound" in scientific discussions, especially in chemistry, biology, or health-related topics. When talking about cleaning products or disinfectants, you might mention that they contain these compounds.
