USE: 2-Naphthol is used in dyes and pigments and to make other chemicals. Azo Dyes • Azo dye is a large class of synthetic organic dyes that contain nitrogen as the azo group −N=N− as primary chromophore their molecular structures. Azo compounds account for more than half of modern dyes. The first direct dye was Congo red, discovered in 1884; it has been largely replaced by dyes with superior resistance to acids and to fading. Naphthol definition, either of two isomeric hydroxyl derivatives, C10H7OH, of naphthalene (alpha-naphthol, or 1-naphthol, and beta-naphthol, or 2-naphthol ), white or yellowish crystals, with a phenolic odor, that darken on exposure to light: used chiefly in dyes, drugs, perfumes, and insecticides. The use of an azo dye as an indicator - methyl orange 2-Naphthol aniline dye. Nitro and Nitroso Dyes • These dyes contain nitro or nitroso groups as the chromophores and –OH as auxochrome.
