Application

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

Features and Benefits

Greener solvent

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.
