  • Applications

    2-Naphthyl formate (CAS 1988-18-7) is an aromatic ester commonly evaluated for fragrance chemistry, where it may act as an odorant or fragrance precursor in perfumery and be used as a fragrance component in cosmetics and personal care products. It can also function as a solvent or processing aid in specialty coatings, inks, and adhesives, and may serve as an organic synthesis intermediate in industrial manufacturing. In polymer and plastics contexts it may be employed as a reactive intermediate within certain formulations, with additional use as a fragrance additive in household products, all subject to regulatory limits.
