Hazard Information | Back Directory | [Production Methods]
Benzidine-3,3' -dicarboxylic acid is made by reducing 2-nitrobenzoic acid with zinc dust and sodium hydroxide solution. The resultant hydrazobenzene-2,2' -dicarboxylic acid is rearranged by heating with hydrochloric acid. The free benzidine-3,3' -dicarboxylic acid is precipitated from the hydrochloric acid solution by adding ammonia or sodium acetate. Electrolytic reduction followed by rearrangement with dilute sulfuric acid is also possible
| [Safety Profile]
Questionable carcinogen withexperimental tumorigenic data. Mutation data reported.When heated to decomposition it emits toxic fumes ofNOx. |
