Heptane is used in a variety of ways besides as a solvent in chemistry classes. N-heptane is a clear, liquid that has a strong gasoline like scent. A simple way to remember this concept is the phrase "like dissolves like." When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane). While heptane is made through a refinery and distillation process of crude oil, it can also be found in nature. At room temperature, heptane exists as a colorless liquid.
