Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Mutation data reported. When heated to decomposition it emits very toxic fumes of NO_x and HCl.

 O-Anisidine hydrochloride (CAS NO.134-29-2) may be carcinogenic. It reacts as an acid to neutralize bases. These neutralizations generate some heat, usually does not react as either oxidizing agents or reducing agents but such behavior is not impossible.It  may catalyze organic reactions.
