Use:
Methyl-carbonate can be used in synthesis polycarbonate.
It can be used to synthesize anti-infections drugs.
It can be used to produce methyl isocyanate.
Methyl-carbonatecan replace dimethyl sulfate to produce benzaldehyde and replace chloromethane to produce TMAN. Methyl-carbonate can replace toxic phosgene as the carbonyl agent.
Methyl-carbonate can used in solvent, electrolyte, dye, etc.
