methylhexane

Methylhexane is a chemical compound with the molecular formula C7H16. It is a branched alkane, meaning it is a saturated hydrocarbon with a seven-carbon chain and a methyl group attached. Specifically, it refers to 2-methylhexane, where the methyl group is attached to the second carbon atom of a hexane chain. Other isomers of heptane also exist, but "methylhexane" typically denotes this specific structure in common usage.

As an alkane, methylhexane is relatively unreactive and is a nonpolar molecule. It is a colorless liquid at room temperature and pressure, and it is flammable. Like other alkanes, it is soluble in organic solvents but not in water. Methylhexane is a component of gasoline and is often found in petroleum distillates. Its presence and concentration can influence the octane rating of fuels. In laboratory settings, it can be synthesized through various organic reactions. It is primarily used as a solvent or as a reference compound in analytical chemistry due to its well-defined properties.
