Cas no 1528-30-9 (Methylenecyclopentane)

Methylenecyclopentane (C6H10) is a cyclic olefin characterized by a five-membered ring with an exocyclic methylene group. This compound is notable for its reactivity in polymerization and addition reactions, making it a valuable intermediate in organic synthesis and specialty chemical production. Its strained ring structure enhances its utility in ring-opening metathesis polymerization (ROMP) and Diels-Alder reactions. Methylenecyclopentane exhibits moderate stability under standard conditions but requires careful handling due to its flammability. Its applications include the synthesis of pharmaceuticals, agrochemicals, and advanced materials. The compound’s distinct structure also facilitates studies in reaction mechanisms and catalytic processes. Storage recommendations typically include inert atmospheres and low temperatures to prevent premature polymerization.
