Industrial Uses

1. Chemical Sythesis

  • Intermediate: DMC is widely used as a safe, eco-friendly methylating agent for the production of methylated products like methyl esters, methyl carbamates, and methyl ethers. It replaces more hazardous methylating agents like dimethyl sulfate or methyl halides.

2. Paints, Coatings & Adhesives

  • Solvent: DMC is an excellent fast-evaporating solvent used in paints, coatings, and adhesives. It is valued for its low toxicity and environmentally friendly profile, often being used in place of more harmful solvents like toluene and acetone.

3. Polymer & Resins

  • Carbonylation Agent: DMC is used to produce polycarbonate plastics through transesterification with bisphenol A, offering a non-phosgene route that is safer and more environmentally friendly compared to traditional phosgene-based processes.

4. Pharmaceuticals 

  • Pharmaceutical Intermediates: DMC acts as an intermediate in the synthesis of pharmaceutical compounds, particularly where methylation reactions are required to build active ingredients or intermediates in a cleaner and safer way.

5. Agrochemicals 

  • Intermediate: Used in the synthesis of herbicides, pesticides, and fungicides, DMC provides a greener alternative for introducing methyl groups during the production of agrochemical compounds.

6. Lubricants & Automobiles

  • Intermediate: DMC is a key component in the electrolyte formulations for lithium-ion batteries. It helps improve the battery’s ionic conductivity and thermal stability, making it vital in the production of batteries for electronics and electric vehicles.
