Used as a key intermediate in the synthesis of fine chemicals and pharmaceuticals, particularly in the preparation of chiral auxiliaries and asymmetric synthesis. It serves as a building block for lactone-containing compounds due to its cyclic carbonate structure, which can undergo ring-opening reactions with nucleophiles such as amines, alcohols, and thiols. Commonly applied in the development of biodegradable polymers and as a solvent or additive in lithium-ion battery electrolytes, where it improves thermal stability and enhances electrode performance. Also utilized in the fragrance industry for the controlled release of active ingredients owing to its ability to form stable derivatives.
