  • Applications

    Cyclopentyl methyl ketone — CAS number: 6004-60-0 — is primarily used as an intermediate in the synthesis of cyclopentyl-containing compounds for pharmaceutical and agrochemical applications. In the fragrance and flavor sector, it is used as an aroma intermediate or building block to generate fragrance notes and cyclopentyl-derived derivatives. As a synthetic building block, CPMK also finds use in materials chemistry to access cyclopentyl motifs for polymers and related materials. Additionally, it is employed in research and development as a starting material for process development and exploration of new chemical libraries.
