Isopentane is a pentane isomer. Isopentane, C5H12, also called methylbutane or 2-methylbutane, is a branched-chain alkane with five carbon atoms. Isopentane is an extremely volatile and flammable liquid at room temperature and pressure. The normal boiling point is just a few degrees above room temperature. It is a colorless and odorless liquid. Isopentane can be mixed with n-pentane to make EPS and it also can be mixed with cyclopentane as a foaming agent for rigid urethane foam. It is also used to produce toothpastes and cosmetics. As an anesthetic, isopentane is less potent than the shorter-chain alkanes; however, it appears more active metabolically.
