Octane is a hydrocaurbon an an alkane wi the chemical formula C₈H₁₈, an the condensed structural formula CH₃(CH₂)₆CH₃. Octane haes mony structural isomers that differ bi the amoont an location o branchin in the carbon chain. Ane o these isomers, 2,2,4-trimethylpentane (isooctane) is uised as ane o the staundart values in the octane ratin scale.

As wi aw law-molecular wicht hydrocarbons, octane an its isomers are very flammable an are components o petrol (petrol).
