What is 4-Amino-5-hydroxy-6-[[4'-[(1-hydroxy-6-phenylamino-3-sodiosulfo-2-naphthalenyl)azo]-1,1'-biphenyl-4-yl]azo]naphthalene-1,3-disulfonic acid disodium salt?

Preparation

4-(4-Aminophenyl)benzenamine double nitriding, in alkaline conditions and has 4-Hydroxy-7-(phenylamino)naphthalene-2-sulfonic acid and 4-Amino-5-hydroxynaphthalene-1,3-disulfonic acid coupling.

Properties and Applications

red light blue. Soluble in water for red light blue, also soluble in soluble fiber element, slightly soluble in alcohol, insoluble in other organic solvents. The strong sulfuric acid in blue, diluted dark purple for blue-ray, precipitation. The dye solution to join 10% sodium hydroxide solution is more blue; Add 10% sulfuric acid remains the same.
