  • Applications

    Pentyl furoate (CAS 1334-82-3) is primarily used as a fragrance ingredient in perfumery and cosmetics, contributing fruity/green notes and sometimes serving as a minor fixative in formulations. It is also employed in household and cleaning products as a scent component to impart pleasant aromas. In industrial manufacturing, coatings, and inks, it may be added as an aroma additive or odorant in fragrance-enhanced formulations. The ester can function as an intermediate in organic synthesis, enabling further chemical transformations. Use in specific applications is subject to local regulations and formulation limits.
