Isopentane for Refrigerants – High-Purity Solvent & Industrial Applications
Introduction
Isopentane for Refrigerants is a high-purity, colorless, and highly volatile hydrocarbon (C₅H₁₂) with a pleasant aromatic odor. Its low boiling point (27.8 °C) and excellent stability make it ideal for industrial and laboratory applications. Widely used as a refrigerant, solvent, and foaming agent, Isopentane delivers reliable performance in HVAC systems, foam production, and organic synthesis reactions.
