3-[[4-[(4-Amino-2-chloro-5-methoxyphenyl)azo]-6-sulfo-1-naphtyl]azo]-4-hydroxy-2-naphthalenesulfonic acid disodium salt Usage And Synthesis

Preparation

2′-Methoxy-4′-amino-5′-chlorooxanilic acid diazo, and 5-Aminonaphthalene-2-sulfonic acid coupling, product to diazo, and 4-Hydroxynaphthalene-2-sulfonic acid coupling, and then 2-(4-Aminophenylamino)-2-oxoacetic acid hydrolysis base.

Properties and Applications

blue. Slightly soluble in water for sauce red to violet black, soluble in ethanol to blue. The strong sulfuric acid for blue-ray green, diluted to blue-ray for blue purple, have precipitation. The dye solution to join strong hydrochloric acid have dark purple precipitation; concentrated sodium hydroxide solution with dark purple precipitate; Add 10% of sulfuric acid and sodium hydroxide solution not change color.
