Denaturant
Denatonium benzoate is widely incorporated into ethanol and other alcoholic beverages to render them undrinkable and thus exempt from beverage alcohol taxes. This prevents misuse as a potable alcohol.
Aversive Agent
It is added to a variety of consumer products, including antifreeze, cleaning fluids, and pesticides, to deter accidental ingestion by children and animals due to its extremely unpleasant taste.
Bitterness Inducer in Research
In chemical synthesis and research, it can be used as a model compound for studying taste receptor interactions or in developing new bittering agents for specific applications.
