Used as a blowing agent in the production of polystyrene foam for insulation and packaging due to its low boiling point and ability to expand polymers. Commonly employed as a solvent in laboratories for extraction and purification processes, especially in the pharmaceutical and chemical industries. Serves as a calibration standard in gas chromatography because of its predictable volatility and clean combustion. Also utilized in some adhesives and coatings formulations as a carrier solvent to control viscosity and drying time. Occasionally used in specialty fuels and as a component in lighter fluids.
