Used primarily as a monomer in the synthesis of biodegradable polymers, particularly aliphatic polyesters. These polymers are applied in drug delivery systems due to their controlled degradation and biocompatibility. Also employed in the production of environmentally friendly plastics for packaging and agricultural films, where gradual breakdown is advantageous. Its cyclic carbonate structure enables ring-opening polymerization, allowing precise tuning of polymer properties such as flexibility, strength, and degradation rate.
