Isobutane, also known as i-butane, 2-methylpropane, or methylpropane, is a chemical compound with molecular formula HC(CH3)3. It is an isomer of butane. Isobutane is a colorless, odorless gas. It is the simplest alkane with a tertiary carbon. A by-product of natural gas processing and petroleum refining, it is commonly used in the welding industry and for instrument calibration. Similar to butane and isobutane, propane is one of a group of liquefied petroleum gases (LPG).
99.5% Ultra-High Purity (UHP) instrument grade isobutane is broadly used in the welding industry and for Instrumentation in refineries, analytical labs, and even in the production of aerosols.
