  • Applications

    4-Methoxy-1-naphthol (CAS 84-85-5) is primarily used as a building block in color chemistry, serving as a coupling component in the production of dyes and pigments for textiles, coatings, and inks. It also functions as a precursor in organic synthesis for pharmaceutical and other specialty chemical intermediates. In plastics and polymer formulations, it may act as a color precursor or starting material for color-containing materials. In research and development settings, it is evaluated for color chemistry and for further derivatization, with uses governed by local regulations and formulation limits.
