Application

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