Nonane

Nonane is a linear alkane hydrocarbon with the chemical formula C₉H₂₀. It is a colorless, flammable liquid, occurring primarily in the component of the petroleum distillate fraction commonly called kerosene, which is used as a heating, tractor, and jet fuel. Nonane is also used as a solvent, distillation chaser, fuel additive, and a component in biodegradable detergents.

Nonane has 35 structural isomers.

Its substituent form is nonyl. Its cycloalkane counterpart is cyclononane, (C₉H₁₈).

Unlike most alkanes, the numeric prefix in its name is from Latin, not Greek. (A name using a Greek prefix would be enneane.)
