Denatonium Benzoate usually known as denatonium, is the most bitter chemical compound analyzed, with very low bitterness thresholds (0.05 ppm). Discovered in 1958, it is a quaternary ammonium cation usually detected as a salt, such as benzoate or saccharinate. It is extracted from the quaternization of lidocaine with benzyl chloride or similar reagents. Denatonium is colorless, and odorless, and is utilized mostly as a frigid agent to forbid ingestion of hazardous substances.
CAS No.: 3734-33-6
