Dimethyl carbonate (DMC, CAS 616-38-6) is a versatile, low-toxicity organic carbonate used widely as a green solvent and as a reactive methylating/transesterification reagent in industrial chemistry. It is valued for its favorable environmental profile compared with traditional methylating reagents, and for its role as a lightweight, low-polarity carbonate solvent in coatings, chemical synthesis and formulation applications. Commercial grades are supplied for solvent, reagent and battery-electrolyte uses with lot-specific Certificates of Analysis describing assay and impurity limits.
