octane
Sign in to saveOctane is a hydrocarbon and also an alkane with the chemical formula C8H18, and the condensed structural formula CH3(CH2)6CH3. Octane has many structural isomers that differ by the 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.
AI overview
Octane is a hydrocarbon compound made of eight carbon atoms and eighteen hydrogen atoms that exists in several different structural forms. It's important because one particular form of octane, called iso-octane, serves as a standard reference point for measuring the octane rating of gasoline.

Octane is a component of gasoline and petroleum. Under standard temperature and pressure, octane is an odorless, colorless liquid. Like other short-chained alkanes with a low molecular weight, it is volatile, flammable, and toxic. Octane is 1.2 to 2 times more toxic than heptane.
