What is a Dimethyl carbonate (DMC) ?

Dimethyl carbonate (DMC) is a colorless, transparent organic compound with a slightly sweet odor, known for its low toxicity and environmentally friendly properties, classified as a carbonate ester synthesized primarily from methanol and carbon dioxide, and it is widely used due to its excellent solvency and reactivity in applications such as paints, adhesives, lithium battery electrolytes, and intermediates for organic synthesis (e.g., polycarbonates and pharmaceuticals), attracting increasing attention as a green chemical alternative to traditional harmful methylating agents (e.g., dimethyl sulfate) and solvents (e.g., acetonitrile), and while it is flammable and can ignite under high temperatures or sparks, requiring proper ventilation, anti-static measures, and solvent-resistant gloves during handling, it is globally expanding as a next-generation chemical material that balances safety and environmental sustainability.
