[Safety Profile]

Mutation data reported. Whenheated to decomposition it emits toxic vapors of NOx.
[Purification Methods]

Crystallise the benzidine from EtOH or pet ether, then from pet ether/*benzene, and sublime it in a vacuum. [Guarr et al. J Am Chem Soc 107 5104 1985.] Dry it in vacuo in a drying pistol, or a vacuum line. It has m 195-196o after sublimation. [Beilstein 13 H 221, 13 I 61, 13 II 97, 13 III 429, 13 IV 368.]
