Preparation

4-Acetamido-2-aminobenzenesulfonic acid diazo, and 5-Amino-7-ehtoxy-2-naphthalenesulfonic acid coupling, again diazo, and 7-(4-Aminobenzamido)-4-hydroxynaphthalene-2-sulfonic acid?coupling, its product to diazo, and 3-Methyl-1-phenyl-1H-pyrazol-5(4H)-one coupling, and then hydrolysis acetyl amino (with aqueous ammonia in Pyridine medium The second step coupled).

Properties and Applications

dark yellow light green. Soluble in water for yellow green, soluble in ethanol. The strong sulfuric acid for olive yellow, diluted for green light. The dye solution to join strong hydrochloric acid have yellow green precipitation; Add thick sodium hydroxide solution for olive green, precipitation.
