  • Applications

    Cyclopentanemethanol (CAS 3637-61-4) is primarily used as a chemical intermediate in the synthesis of cyclopentyl-containing fragrance and flavor compounds, serving as a building block for esters and ethers used in perfumery and taste formulations. It also serves as a precursor for cyclopentyl methyl ether (CPME), a greener solvent widely employed in organic synthesis and in industrial applications such as coatings, polymer processing, and electronics. In pharmaceutical and agrochemical development, it is considered a scaffold for constructing cyclopentyl-containing pharmacophores and related intermediates. In polymer and coating chemistry, it can function as a specialty intermediate or processing aid for resin formulations and adhesion-related applications. Additionally, it may be used in cosmetics and personal care formulations via its role as a fragrance-building block.
