Product Description
3,3'-Diaminobenzidine can be used as organic synthesis intermediates and pharmaceutical intermediates. (1) 3,3'-Dichlorobenzidine is a raw material, and it is obtained by reacting with ammonia under the action of a copper catalyst; (2) Using benzidine as a raw material, it reacts with acetic acid to produce biphenyl diacetamide, and then reacts with nitric acid Chemicalbook to produce 3,3`-dinitrobiphenyl diacetamide, which is hydrolyzed in aqueous sulfuric acid to produce 3,3`- Dinitrobenzidine is finally obtained by reduction with sodium sulfide or catalytic hydrogenation reduction.
