It is an important raw material and intermediate used in organic synthesis, dyestuffs and in agrochemical industries. It is used in medicine. Cyclohexene oxide (epoxycyclohexane) is an useful monomer in polymerization and coating industry. It is used in the synthesis of alicyclic target materials including pharmaceuticals, perfumery and dyestuffs. It is used as a monomer in photopolymerizations, with carbonmonoxide to yield aromatic polycarbonates which has minimum impurities.


Store at room temperature. Incompatible with oxidizing agents.
