N,N,N',N'-TETRAMETHYLBENZIDINE Chemical Properties,Usage,Production

Chemical Properties

solid

Synthesis Reference(s)

Tetrahedron Letters, 13, p. 2193, 1972 DOI: 10.1016/S0040-4039(01)84803-6

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.]
