  • Applications

    2-Methyl-1,5-heptadien-4-ol (CAS 926-98-7) may serve as an intermediate and scent-related ingredient across several industries. In perfumery and cosmetics, it can function as an odorant or fragrance component and as a building block for downstream fragrance chemistry. In the flavor sector, it is commonly evaluated as a flavor precursor in aroma formulations. In coatings and inks, it may be used as a specialty additive or fragrance modifier. In polymers and plastics, it is sometimes explored as a precursor or functionalizable monomer for specialty polymers. In industrial manufacturing more broadly, it is used as a chemical building block in fragrance chemistry and related formulations, subject to regulatory and formulation limits.
