(3Z)-3-[[2-methyl-4-(2-methylphenyl)diazenyl-phenyl]hydrazinylidene]-4-oxo-naphthalene-1-sulfonic acid Usage And Synthesis

Preparation

2-Methyl-4-(o-tolyldiazenyl)benzenamine diazo, coupled with the 4-Hydroxynaphthalene-1-sulfonic acid.

Properties and Applications

blue-ray red. Slightly soluble in water, soluble in ethanol right amount to red. In the strong sulfuric acid as dark blue, diluted as a light red orange. In water solution to join strong hydrochloric acid have red brown precipitation; With strong sodium hydroxide solution for wine red, and then generate a purplish red precipitate.
