Description

Isopentane CAS NO 78-78-4 is a highly volatile, branched-chain alkane hydrocarbon with the molecular formula C5H12. Its low boiling point and excellent solvent properties make it a critical component in numerous industrial and scientific processes. This chemical is essential for manufacturers and researchers in the polymer, refrigeration, and analytical sectors who require a reliable, high-purity blowing agent, refrigerant, or extraction solvent.

Application

• Primary blowing agent in the production of expanded polystyrene (EPS) and polyurethane foams.
• Key component in refrigerant blends and as a low-temperature working fluid in specialized cooling systems.
• Used as a solvent for polymerization reactions, extraction processes, and in chromatography.
• Acts as a precursor in organic synthesis and the manufacture of other chemicals like isoprene.
• Employed as a fuel component and an additive to adjust the vapor pressure of gasoline.
• Serves as a calorimetry standard and a reference fluid in laboratory and analytical applications.
