Dimethyl carbonate (DMC) is an organic compound with the formula OC(OCH3)2. It is a colourless, flammable liquid. It is classified as a carbonate ester. This compound has found use as a methylating agent and as a co-solvent in lithium-ion batteries.[1] Notably, dimethyl carbonate is a weak methylating agent, and is not considered as a carcinogen.[2] Instead, dimethyl carbonate is often considered to be a green reagent,[3][4] and it is exempt from the restrictions placed on most volatile organic compounds (VOCs) in the United States.[5]
