Preparation

3,3′-Dimethylbenzidine double nitriding,first coupled with 2-Hydroxybenzoic acid, and then in alkaline conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, its product to diazo, and Benzene-1,3-diamine coupling.

Properties and Applications

brown olive green light. Soluble in water for olive brown, and adequate soluble in alcohol. The strong sulfuric acid in dark red light blue to for purple, for olive diluted. The dye solution to join strong hydrochloric acid have dark brown precipitation; Join the red sulfuric acid 10%; Add thick sodium hydroxide solution have yellow brown precipitation.
