1. DMC /dimethyl carbonate/ can be used in the synthesis of important pharmaceuticals, such as the antimicrobial ciprofloxacin (Cipro) where it is used in place of diethyl malonate, and in the preparation of guaifenesin, a precursor for the muscle relaxant, methocarbamol.
2. Used primarily in the synthesis of bisphenol A polycarbonates.
3. Environmentally benign substitute for dimethyl sulfate and methyl halides in methylation reactions for phosgene.
4. DMC /dimethyl carbonate/ is also finding increasing application in the field of rechargable lithium batteries as a nonaqueous electrolyte component, as well as a blowing agent in polyurethane foam.
