Direct Violet 51 is an azo dye with a λmax of 549 nm.

Preparation

2-Amino-3,5-dimethylbenzenesulfonic acid diazo, and 2-Amino-4-methylanisole coupling, its product to diazo, in alkaline conditions and 4-Hydroxy-7-(phenylamino)naphthalene-2-sulfonic acid coupling.

Properties and Applications

blue purple. Purple powder. For the red light purple is soluble in water, soluble in soluble fiber element, slightly soluble in ethanol and acetone, insoluble in other organic solvents.
