Cyclopentene is used in the production of cyclopentene oxide, ketamine, cyclopentyl phenol (disinfectant), aldehyde and cyclopentene glycol. It acts as a monomer and is utilized for the synthesis of plastics and in various chemical syntheses. It is also used in the investigation of [2+2] cycloaddition of diamond (001) surfaces with alkene.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
