Heptane is a hydrocarbon from the alkanes family. Heptane (and its isomers) is widely used as a non-polar solvent in laboratories. The liquid is suitable for transportation and storage. In the grease spot test, heptane is used to dissolve the oil spot from the stain and shows a number of organic compounds of a particular material. This is done by shaking the stained paper in a heptane solution for about half a minute. Extraction inside heptane is the name of the method that identifies bromine from iodine. Heptane is also commercially used as a solvent for rubber and fuel glue solvent. The number of n-Heptane octanes is negative, and its presence in gasoline is undesirable and usually, causes an explosion. It is a member of the family of saturated aliphatic hydrocarbons, Alkan.

Indications:

Heptane and its isomers are widely used in solvents for laboratories. In the test of the spot test, heptane is used to dissolve the oily specimen to show a number of organic compounds present in it. Extraction from heptane means identification of bromine solutions from iodine. Heptane is commercially available for rubber and fuel glue.
