Isopentane(2-Methylbutane), purity 95%, 99%, in Isotank and drums

Product Description
Iso-pentane(2-Methylbutane)  Applications.
Isopentanes are some of the primary blowing agents used in the production of polystyrene foam and other foams. Usually, a mixture of n-, i-, and increasingly cyclopentane is used for this purpose. Because of its low boiling point, low cost, and relative safety, pentane is used as a working medium in geothermal power stations. It is added into some refrigerant blends as well.
Isopentanes are relatively inexpensive and are the most volatile alkanes that are liquid at room temperature, so they are often used in the laboratory as solvents that can be conveniently evaporated. Pentanes are miscible with most common nonpolar solvents such as chlorocarbons, aromatics, and ethers. They are also often used in liquid chromatography.  Isopentane is also used in a closed loop in geothermal power production to drive turbines. Isopentane is used, in conjunction with dry ice or liquid nitrogen, to freeze tissues for cryosectioning in histology.

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.
