n-Heptane is a colorless, flammable liquid hydrocarbon with a characteristic gasoline-like odor. It is one of the straight-chain alkanes and is primarily used as a solvent in various industrial applications. n-Heptane is widely employed in laboratories for extraction, chromatography, and as a standard in octane rating tests. It is also utilized in the manufacturing of rubber, coatings, and adhesives. Additionally, n-Heptane serves as a calibration standard in gas chromatography due to its well-defined physical properties and low reactivity. However, due to its flammable nature, proper storage and handling procedures are necessary to prevent accidents.
