  • Applications

    5-Phenylpentan-1-ol (CAS 10521-91-2) is primarily used as an intermediate in fragrance chemistry, where it is converted into fragrance compounds and odorants for perfumery and cosmetics. It is commonly evaluated as a precursor for aroma esters in flavor and personal-care formulations, contributing to scent profiles in perfumes, lotions, and cleaners. In polymer and plastics processing, it can serve as a building block for specialty polyesters or other functional organic intermediates. Additionally, it may participate in industrial manufacturing workflows as a versatile intermediate for further functionalization to access more complex aroma- or specialty compounds.
