  • Applications

    1-Cyclopentylethanol (CAS 52829-98-8) is primarily used as an intermediate in the synthesis of cyclopentyl-containing specialty chemicals and may serve as a solvent or processing aid in industrial manufacturing. It acts as a building block for fragrance and flavor-related compounds and is used in the cosmetics and personal-care sector as a solvent or formulation component. In coatings, inks, and adhesives, it can function as a processing solvent or carrier. It is also evaluated as a chiral building block for pharmaceutical synthesis and related intermediates. Additionally, it may be employed in cleaning formulations as a solvent or co-solvent and in polymer/plastics processing as a processing aid or modifier. Subject to local regulations and formulation limits.
