N,N,N',N'-Tetramethylbenzidine Usage And Synthesis
Chemical Propertiessolid
Synthesis Reference(s)Tetrahedron Letters, 13, p. 2193, 1972 DOI: 10.1016/S0040-4039(01)84803-6
Safety ProfileMutation data reported. Whenheated to decomposition it emits toxic vapors of NOx.
Purification MethodsCrystallise 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.]
