  • Applications

    2-Methyl-1-naphthol (CAS 7469-77-4) is commonly used as an intermediate in the synthesis of dyes and pigments, including azo colorants for textiles, inks, and coatings. It also serves as a building block in fragrance chemistry, where it can be converted into aroma compounds or used as an odorant precursor. In polymer and coatings applications, it may function as a precursor for specialty resins or as a handle for surface functionalization. It may be evaluated for use in cosmetics and personal care as a fragrance component or dye intermediate. Additionally, it can serve as a synthetic building block in pharmaceutical and agrochemical research.
