  • Applications

    Cyclopentanol, 2-(2-hexenyl)- is primarily used as an organic intermediate in fragrance chemistry, serving as a versatile building block for aroma compounds and as a precursor for further functionalization to access diverse notes. In cosmetics and personal care, it is employed as a fragrance ingredient or intermediate, contributing to fragrance profiles in products such as creams and lotions. In industrial manufacturing, it functions as an intermediate for the synthesis of specialty chemicals and polymer precursors that incorporate fragrance functionality. In coatings and inks, it can be used as a processing intermediate or reactive diluent for fragrance-bearing formulations. It may also be encountered as a solvent or co-solvent in niche formulation workflows, subject to regulatory controls. CAS 34686-67-4.
