Uses

Acid orange 51 is an azo dye.

Preparation

2-(4-Aminophenylamino)-5-nitrobenzenesulfonic acid diazotization and 5-Aminonaphthalene-2-sulfonic acid and 8-Aminonaphthalene-2-sulfonic acid coupling, and its product and diazotization, coupling with o-Cresol, 4-Methylbenzene-1-sulfonyl chlorideand then esterified

Properties and Applications

red light orange. Dark red light orange powder. Soluble in water, ethanol, glycol ether. The strong sulfuric acid dyes for deep blue light green, dilute precipitation after brown; In nitric acid solution for olive, then into amber color.
