  • Applications

    2-Naphthyl benzoate (CAS 93-44-7) is used in fragrance applications as an aroma chemical and potential fixative, commonly incorporated into perfumery and cosmetic formulations to contribute woody and resinous notes. It also serves as an organic synthesis intermediate for specialty esters and dyes, and can be found as a component or processing aid in coatings and inks to improve formulation stability. Additionally, it may be evaluated as a solvent or carrier in niche industrial formulations, and as a starting material for the production of other aromatics, subject to local regulations and formulation limits.
