Used primarily as a blowing agent in the production of polyurethane and polystyrene foams, providing efficient expansion and insulation properties. Commonly employed in refrigerant blends due to its low boiling point and favorable thermodynamic characteristics. Also utilized as a solvent in laboratories for extraction and purification processes where low polarity and volatility are required. Frequently serves as a calibration standard in gas chromatography owing to its predictable vapor behavior. Occasionally used in specialty aerosol applications as a propellant.
