ChEBI: An organic sodium salt that is the disodium salt of 4,5-dihydroxy-3-(phenyldiazenyl)naphthalene-2,7-disulfonic acid. It is used as the plasma stain in trichrome techniques. | [Preparation]
aniline diazo, and 4,5-Dihydroxynaphthalene-2,7-disulfonic acid?coupling. | [Properties and Applications]
red. Soluble in water for red orange, soluble in soluble fiber element, moderate soluble in alcohol and acetone is red light purple, insoluble in other organic solvents. The strong sulfuric acid for wine red, diluted into pink; In nitric acid solution for red, and then to orange. Add hydrochloric acid in aqueous solution for the red orange; Add thick sodium hydroxide solution for deep red wine.
