isobutane

Also known as 2-Methylpropane, (CH3)2CH-CH3, E943b, R-600a, r600a, R600a

Isobutane, also known as '''i-butane, 2-methylpropane or methylpropane''', is a chemical compound with molecular formula HC(CH3)3. An isomer of butane, it is a colorless, odorless gas. Isobutane is the simplest alkane with a tertiary carbon atom, and is used as a precursor molecule in the petrochemical industry, such as in the synthesis of isooctane.
