Overview
Cyclopentene
Cyclopentene is a highly reactive cyclic olefin used as a key monomer and intermediate in agrochemical, pharmaceutical, and specialty polymer production. Its strained five-membered ring readily undergoes addition reactions, ring-opening metathesis polymerization (ROMP), and oxidation to produce a wide range of downstream chemicals. It is a primary feedstock for cyclopentanone, cyclopentanol, glutaric acid, and various agrochemical intermediates. Cyclopentene requires careful handling due to its high volatility and low flash point.
