Anwendungen

Cyclopentanone is used as an intermediate in the synthesis of rubber adhesives, synthetic resins, pharmaceuticals and biologically active compounds. It acts as precursor for the preparation of cyclopentamine and also pentethylcyclanone, cyclopentobarbital. It is a useful laboratory reagent and is used as thinner for epoxies. It can also be used as a solvent in paint and varnish removers and for electronic applications. As a dry cleaning agent, it is used for oil extraction. It is also involved in the preparation of cyclopentanone derivatives like cyclopenylamine and cyclopentanol which find application in the perfume industry.

Bemerkungen

Incompatible with strong reducing agents, strong oxidizing agents and strong bases.
