Denatonium benzoate is a kind of quaternary ammonium salt formed by the combination of the quaternary ammonium cation and inert anion such as benzoic acid or saccharin anion. The structure of its cation form is similar to that of a local anesthetic lidocaine with the only difference being an additional benzyl functional group located on the nitrogen atom of the amino.
