Dimethyl carbonate, often abbreviated DMC is a flammable clear liquid boiling at 90 °C, insoluble in water. It is a methylating reagent which has found use recently. Its main benefit over other methylating reagents such as iodomethane and dimethyl sulfate is its lesser toxicity and biodegradability.[1] Also, it is now prepared from catalytic oxidative carbonylation of methanol with oxygen, instead of from from phosgene making its production non-toxic and environmentally friendly.[1] This makes dimethyl carbonate quite a green reagent.
