Propylene carbonate（Cat No.:R061663）is a colorless, odorless, and highly polar organic compound with the molecular formula C4H6O3. It is a cyclic carbonate ester derived from propylene glycol and carbonic acid. This versatile solvent is widely used in lithium-ion battery electrolytes, paint strippers, adhesives, and personal care products due to its high dielectric constant and low volatility. Propylene carbonate is also employed in CO₂ capture, polymer processing, and as a medium for organic reactions. It is biodegradable and considered a safer, environmentally friendly alternative to more toxic solvents in various industrial and laboratory applications.
