2-Naphthalenesulfonic acid, 7-[[[[4-(acetylamino)phenyl]amino]carbonyl]amino]-3-[[4-[(2,4-dichloro-6-sulfophenyl)azo]-3-methylphenyl]azo]-4-hydroxy-, disodium salt Chemical Properties,Uses,Production

Preparation

2-Amino-3,5-dichlorobenzenesulfonic acid?diazo, and m-Toluidine coupling, and then a sulfonic acid hydrolysis off base, again diazo, and 7-(3-(4-Acetamidophenyl)ureido)-4-hydroxynaphthalene-2-sulfonic acid coupling.

Properties and Applications

blue-ray red. Soluble in water for product red to blue light red, soluble in ethanol in red. In the strong sulfuric acid as dark blue, diluted red for blue-ray. The dye solution to join strong hydrochloric acid have purplish red precipitate; Add sodium hydroxide solution have strong purplish red precipitate.
