Used as a key intermediate in the synthesis of lithium-ion battery electrolytes, particularly in the production of fluoroethylene carbonate (FEC), which enhances the stability and performance of the solid electrolyte interphase (SEI) layer on silicon-based anodes. It also serves in the preparation of specialty polymers and as a derivatizing agent in organic synthesis due to its ability to introduce carbonate functionalities under mild conditions. Its cyclic carbonate structure makes it valuable in creating biodegradable plastics and as a solvent or additive in electrochemical applications.
