Heptane and its many isomers are 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.

Heptane is also used as an adhesive remover by stamp collectors.
