What is 5-Amino-4-hydroxy-3-[[4'-[(1-hydroxy-4-sulfonaphthalen-2-yl)azo]-3,3'-dimethyl[1,1'-biphenyl]-4-yl]azo]-2,7-naphthalenedisulfonic acid trisodium salt?
Preparation
3,3′-Dimethylbenzidine double nitriding, in alkaline conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, and then and 4-Hydroxynaphthalene-1-sulfonic acid coupling.
Properties and Applications
dark red to blue light blue. Soluble in water for the navy, slightly soluble in ethanol is shallow purple, slightly soluble in soluble fiber element, insoluble in other organic solvents. The strong sulfuric acid in blue, diluted red for purple; In the nitric acid blue, to brown. The dye solution to join strong hydrochloric acid for purple, precipitation; Add thick sodium hydroxide solution for wine red, have precipitation.
