2,7-Naphthalenedisulfonic acid, 4-amino-3-[[4-[[[[4-[(6-amino-1-hydroxy-3-sulfo-2-naphthalenyl)azo]phenyl]amino]carbonyl]amino]phenyl]azo]-5-hydroxy-, trisodium salt Chemical Properties,Uses,Production

Preparation

1,3-Bis(4-aminophenyl)urea double nitriding, in alkaline conditions and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid coupling, in acid conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling.

Properties and Applications

bright purple. Soluble in water (for red light purple) and ethanol, easily soluble in soluble fiber element, insoluble in other organic solvents. The strong sulfuric acid for purple, dilute for dark blue purple solution after, precipitation. The dye solution to join 10% no change sulfuric acid; Add 10% sodium hydroxide solution for purplish red color.
