5-Amino-2-hydroxybenzoic acid?diazo, and?2-(1-Amino-6-sulfonaphthalen-2-yloxy)acetic acid?coupling, again diazo, and 6-(4-Benzamidoanilino)-1-naphthol-3-sulfonic acid?coupling (finally coupling is with aqueous ammonia in Pyridine medium). | [Properties and Applications]
green light blue. Soluble in water for blue, slightly soluble in alcohol. In the dark for the strong sulfuric acid, diluted green solution for blue-ray, accompanied by precipitation. The dye solution to join strong hydrochloric acid have dark blue light green precipitation; With strong sodium hydroxide solution for blue light green, precipitation.
