4-(PHENYLAZO)DIPHENYLAMINE Usage And Synthesis

Chemical Properties

orange fine crystalline powder

Uses

4-(Phenylazo)diphenylamine is a soluble azo dye and stain. Dyes and metabolites.

Safety Profile

Poison by intravenous route. When heated to decomposition it emits toxic vapors of NOx.

Purification Methods

Purify the dye by chromatography on neutral alumina using dry *C6H6 with 1% of dry MeOH. The major component, which gave a stationary band, is cut out and eluted with EtOH or MeOH. [H.gfeldt & Bigeleisen J Am Chem Soc 82 15 1960.] It crystallises from pet ether, EtOH or aqueous EtOH, and has max at 420nm ( 28,000) (aqueous EtOH) and 540nm (aqueous EtOH/H2SO4) [Badger et al. J Chem Soc 1888 1954, Beilstein 16 H 314, 16 III 343, 16 IV 457.]
