Metabolite Identification
Common NameOctane
DescriptionOctane, also known as N-oktanis a hydrocarbon and an alkane with the chemical formula C8H18, and the condensed structural formula CH3(CH2)6CH3. Octane has many structural isomers that differ by the amount and location of branching in the carbon chain. One of these isomers, 2,2,4-trimethylpentane (commonly called iso-octane) is used as one of the standard values in the octane rating scale. Octane belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2, and therefore consisting entirely of hydrogen atoms and saturated carbon atoms. Thus, octane is considered to be a hydrocarbon lipid molecule. Octane is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Octane is an alkane and gasoline tasting compound. Outside of the human body, octane has been detected, but not quantified in several different foods, such as pepper (Capsicum annuum), celery stalks, cauliflowers, alcoholic beverages, and corns. One of the isomers, 2,2,4-trimethylpentane or isooctane, is of major importance, as it has been selected as the 100 point on the octane rating scale, with n-heptane as the zero point. Octane is an alkane with the chemical formula C8H18. Octane is a potentially toxic compound. Treatment is mainly symptomatic and supportive. It has 18 isomers. Octane ratings are ratings used to represent the anti-knock performance of petroleum-based fuels (octane is less likely to prematurely combust under pressure than heptane), given as the percentage of 2,2,4-trimethylpentane in an 2,2,4-trimethylpentane / n-heptane mixture that would have the same performance.
