2-Methylbutane, Synonyms: iso-Pentane, Isopentane, CAS# 78-78-4, chemical formula C₅H₁₂, Molar Mass: 72.15 g/mol, Chemical Formula: C₅H₁₂, EC Number: 201-142-8
Isopentane, also called methylbutane or 2-methylbutane, is a branched-chain saturated hydrocarbon with five carbon atoms, with formula C₅H₁₂ or CH(CH₃). Isopentane is an extremely volatile and extremely flammable liquid at room temperature and pressure. It is also the least dense liquid at standard conditions. The normal boiling point is just a few degrees above room temperature and isopentane will readily boil and evaporate away on a warm day.
