Heptane (and its many isomers) is widely used in laboratories as a non-polar  solvent. As a liquid, it is ideal for transport and storage. In the grease spot test, heptane is used to dissolve an oil spot to show the previous presence of organic compounds on a stained paper. This is done by shaking the stained paper in a heptane solution for about half a minute.

Aqueous bromine may be distinguished from aqueous  iodine by its appearance after  extraction into heptane. In water, both bromine and iodine appear  brown. However, iodine turns purple when dissolved in heptane, whereas the bromine solution remains brown.
