  • Applications

    CAS 18675-17-7, 3,5-Octadien-2-ol, 2,6-dimethyl-, (5E)- is used primarily as an intermediate and building block in fragrance chemistry, where it is employed to synthesize esters and other aroma compounds and can serve as a fragrance ingredient. In cosmetics and personal care, it may function as a scent component or solvent within formulations. It is also encountered in household products as a fragrance additive to impart specific notes in cleaners and detergents. In flavor and fragrance development, it may be evaluated as a precursor that contributes to aroma profiles. In industrial manufacturing, it can act as an intermediate for the synthesis of aroma-related chemicals and optimized fragrance systems, subject to formulation limits and local regulations.
