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.
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.

Eye contact with this substance causes irritation and pain. In small quantities, this substance does not stimulate the skin. But in the long run, it causes irritation, burning, and pain. It has a low toxicity and high levels of nausea and vomiting. Short-acting inhalation can reduce the effectiveness of the central nervous system. Vapors may explode with air at temperatures above 4 ° C.
