These are acyclic branched hydrocarbons having the general formula CnH2n+2. It is a chemical compound with molecular formula HC(CH3)3. It is an isomer of butane. It is the simplest alkane with a tertiary carbon. Propellant/aerating agent used in foods. Recent concerns with depletion of the ozone layer by freon gases have led to increased use of isobutane as a gas for refrigeration systems, especially in domestic refrigerators and freezers, and as a propellant in aerosol sprays. When used as a refrigerant or a propellant, isobutane is also known as R-600a. Some portable camp stoves use a mixture of isobutane with propane, usually 80:20. Isobutane is used as a feedstock in the petrochemical industry, for example in the synthesis of isooctane. Its UN number (for hazardous substances see shipping) is UN 1969. Isobutane is the R group for the amino acid leucine. Isobutane is obtained by isomerization of butane.(CH3)2CH-CH31,1-Dimethylethane2-Hydroxy-2-methylpropanenitrile2-Hydroxyisobutyronitrile2-Methyllactonitrile4-(Hydroxyamino)-N-(5-methyl-3-isoxazolyl)benzenesulfonamide4-(Hydroxyamino)-N-(5-methyl-3-isoxazolyl)benzenesulphonamideA 31 (hydrocarbon)Acetone cyanhydrinAcetone cyanohydrinAlkanes, C4-5Alpha-hydroxyisobutyronitrileButane, branched and linearE943bI-butaneiso-C4H10IsobutaneIsobutane (NF)Isobutane mixturesMethylpropanePropane, 2-methyl-Propane, 2-methyl-isobutaneSmx-haSMX-NHOHSulfamethoxazole hydroxylamineSulphamethoxazole hydroxylamineTert-butaneTrimethylmethaneC4H1058.122258.078250322-methylpropaneisobutane114438-33-4CC(C)CInChI=1S/C4H10/c1-4(2)3/h4H,1-3H3NNPPMTNAJDCUHE-UHFFFAOYSA-N belongs to the class of organic compounds known as branched alkanes.
