Octane or n-octane is an aliphatic straight-chain hydrocarbon with the chemical formula C8H18. While the n form has few uses, one of its isomers, 2,2,4-trimethylpentane is an important component of gasoline and the standard 100 point on the octane rating scale.
Contents
Properties
Chemical
Octane will burn in air in the presence of an ignition source.
Physical
Octane is a colorless liquid, with a petroleum odor, insoluble in water, but miscible with other organic solvents.
Availability
Octane can be extracted from various petroleum solvents, such as Stoddard solvent (which contains a mixture of aliphatic and alicyclic C7 to C12 hydrocarbons), via fractional distillation, though you need a large amount of solvent to obtain any useful amount of n-octane.
Lastly, octane can be purchased from chemical suppliers.

Handling
Safety
Octane vapors are irritant and because it's flammable, it is considered a fire hazard.
Storage
In closed bottles, away from any heat source.
Disposal
Octane can be safely burned.
