Preparation | 4-(4-Aminophenyl)benzenamine double nitriding, first with Naphthalen-1-amine coupling, product diazo again, and then in alkaline conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid(2 Moore) coupled. | Properties and Applications | red light black. Soluble in water for a blue-black, slightly soluble in ethanol for blue-ray gray. The strong sulfuric acid in dark green light blue, diluted as dark blue and purple, have precipitation. The dye solution to join strong hydrochloric acid for blue-ray black to dark blue, precipitation; With strong sodium hydroxide solution for blue-ray black to blue.
