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]
