Alpha-Naphthol (1-Naphthol)
Alpha-naphthol (1-naphthol) is an isomeric phenolic compound used as a coupling component and building block in dye synthesis, pharmaceutical synthesis, and agrochemical production. As a dye intermediate, it provides different coupling selectivity and hue characteristics compared to beta-naphthol, enabling complementary shade ranges including violet and brown azo dyes. Chemzip supplies high-purity alpha-naphthol for industrial and specialty chemical applications.
