Heptane is widely used as a non-polar solvent in laboratories and industrial applications due to its ability to dissolve oils, fats, and other non-polar substances. It serves as a key component in the calibration of octane ratings for gasoline, where it acts as the zero point on the octane scale because of its poor anti-knock properties. In organic synthesis, heptane is employed as a reaction medium or extraction solvent, especially in processes requiring low polarity. It is also found in cleaning agents, adhesives, and as a carrier solvent in pesticide formulations. Due to its volatility and low reactivity, it is useful in controlled evaporation processes and as a standard in gas chromatography.
