  • Applications

    Heptane, 3-ethyl-5-methylene- is a non-polar hydrocarbon widely used as a solvent and diluent in industrial manufacturing, notably in paints, coatings, and inks where it helps dissolve resins and adjust evaporation characteristics. It serves as a cleaning and degreasing solvent for machinery and equipment. In plastics and polymer processing, it acts as a processing solvent or diluent during formulation and some polymerization steps. It is used as an extraction solvent for natural products and essential oils, enabling separation and purification of constituents. In analytical laboratories, it functions as a solvent for chromatography and sample preparation, particularly for non-polar analytes and gas chromatographic (GC) methods. These roles are subject to local regulations and formulation limits.
