General description

Dimethyl carbonate (DMC) is a versatile, non-toxic, biodegradable reagent with tunable chemical reactivity. It serves as a green alternative to dimethyl sulfate or methyl halides and phosgene for methylation and carboxylation reactions. DMC can be prepared by the base-catalyzed reaction between carbon dioxide and methanol.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is a Greener alternative to conventional solvents and chemicals. Click here for more information.

Application

Dimethyl carbonate has been used to dissolve poly (lactic-co-glycolic acid) (PLGA) to form PLGA-coated bioactive glass-ceramic scaffolds.
