Product Description:

(R)-(+)-Propylene carbonate is a chiral, cyclic organic carbonate ester. It is the enantiomer of the widely used solvent propylene carbonate, distinguished by its specific optical rotation. Its molecular structure features a five-membered ring containing a carbonyl group and an oxygen atom, with a methyl group and a chiral center. The primary and significant application of (R)-(+)-propylene carbonate is as a high-purity component or precursor in advanced lithium-ion battery electrolytes. Its high dielectric constant, wide electrochemical stability window, and good solvating power for lithium salts make it valuable for formulating electrolytes aimed at improving battery performance, cycle life, and safety, particularly in high-voltage systems. The chiral form may be investigated for specific effects on ion transport or interfacial properties. Beyond its role in energy storage, this compound serves as a specialty polar aprotic solvent in organic synthesis and as a chiral building block or reagent in asymmetric synthesis and pharmaceutical intermediate preparation. It is also studied in polymer chemistry. Handling requires standard precautions for organic solvents, including adequate ventilation.
