Cyclopentane is a cycloalkane with the chemical formula C5H10. It is a colorless liquid at room temperature and pressure, with a distinct odor. Its structure consists of a five-membered ring of carbon atoms, each bonded to two hydrogen atoms. Cyclopentane is a saturated hydrocarbon, meaning it contains only single bonds between carbon atoms and no double or triple bonds.

Industrially, cyclopentane is primarily produced through the fractional distillation of petroleum. It is also synthesized by the catalytic hydrogenation of cyclopentene. Its principal applications include its use as a blowing agent in the production of polyurethane foams, where it helps create the insulating properties of the foam. It can also serve as a solvent in various chemical processes and as a component in some laboratory reagents.

Cyclopentane is flammable and should be handled with care. It is relatively unreactive due to the absence of strained bonds in its five-membered ring, which is less strained than smaller rings like cyclopropane or cyclobutane. Its boiling point is approximately 49.2 °C. In terms of environmental impact, it is considered a volatile organic compound (VOC).
