Overview
Cyclopentanone

Cyclopentanone is a colorless to pale yellow liquid ketone serving as a critical intermediate in pharmaceutical synthesis, electronic chemicals, and fine chemistry. It is widely used in the production of cyclopentanone-derived APIs, rubber chemicals, and as a high-purity solvent for advanced display and semiconductor processes. Its five-membered ring ketone structure offers unique reactivity for aldol condensations, reductive aminations, and heterocyclic synthesis, making it indispensable in modern pharmaceutical process chemistry.
