Solvent Violet 13, also known as D&C Violet No.2, oil violet, Solvent Blue 90, Alizarine Violet 3B, Alizurol Purple, Duranol Brilliant Violet TG, Ahcoquinone Blue IR base, Quinizarin Blue, Disperse Blue 72, and C.I. 60725, is a synthetic anthraquinone

dye A dye is a colored substance that chemically bonds to the substrate to which it is being applied. This distinguishes dyes from pigments which do not chemically bind to the material they color. Dye is generally applied in an aqueous solution an ...

with bright bluish violet hue. It is a solid insoluble in water and soluble in acetone, toluene, and benzene. Its chemical formula is C₂₁H₁₅NO₃, and its structure is 1-hydroxy-4-(''p''-tolylamino)anthraquinone, or 1-hydroxy-4- 4-methylphenyl)amino9,10-anthracenedione or 1-hydroxy-4-(4-methylanilino)anthraquinone. Solvent Violet 13 is used to dye hydrocarbon products like solvents and petrol, thermoplastics, synthetic resins, e.g.
