  • Applications

    2-Naphthyl lactate, CAS 93-43-6, is used as an intermediate in fragrance chemistry and the synthesis of aromatic esters for the cosmetics and perfumery industries; it can also function as a biochemical substrate for esterases and in histochemical staining, where ester hydrolysis releases 2-naphthol to yield a color signal. Additionally, it serves as a building block for specialty esters in industrial chemical synthesis and cosmetic ingredients, with usage subject to local regulations and formulation limits.
