heptane

Straight-chain hydrocarbon solvent

Heptane is a hydrocarbon with seven carbon atoms, one of the alkanes—the series of simple chain-like molecules that includes methane, propane, and octane.

It's a colorless liquid used as a solvent and as a reference standard for measuring fuel quality: pure heptane defines zero on the octane rating scale, representing maximum engine knock.
