Dimethyl Carbonate (DMC) Supplier China | CAS 616-38-6 | ≥99.9%

Dimethyl Carbonate Product Overview

Dimethyl Carbonate (DMC) is a carbonate ester used as a solvent and reactive building block. It combines moderate polarity, relatively low viscosity and useful volatility with methylating and methoxycarbonylating chemistry under suitable process conditions. Environmental or substitution claims must be evaluated for the complete application; DMC should not be described as universally harmless or as a direct replacement for every conventional solvent.

Typical Industrial Applications

• Coatings, inks and adhesives: solvent or formulation component after compatibility, drying and regulatory evaluation.
• Organic synthesis: methylating, methoxycarbonylating or carbonate reagent under validated reaction conditions.
• Polycarbonate and specialty intermediates: raw material in selected carbonate and fine-chemical processes.
• Battery materials: electrolyte-solvent component only when the grade meets stringent battery-specific water, acid, metals and impurity requirements.
• Process solvent: reaction, extraction or cleaning solvent where its physical properties fit the operation.

Industrial Grade vs Battery Grade

Assay alone does not determine electrolyte suitability. Commercial battery-grade DMC may specify ≥99.9% assay together with water and acidity below 10 ppm, plus additional controls for methanol, metals and other ionic or organic impurities. A general industrial ≥99.9% grade must not be represented as battery grade unless the complete specification, manufacturing controls and batch documentation satisfy the customer’s electrolyte requirements.

COA and Specification Review

Buyers should compare DMC assay, water, acidity, methanol, color, density, non-volatile residue and application-specific trace impurities. For battery applications, review water and acid at ppm level, trace metals and ionic impurities using agreed methods. For synthesis or coatings, methanol, water, acidity and evaporation behavior may be more relevant.

Packaging, Storage and Safety

DMC is a flammable liquid. Packaging and bulk options depend on quantity, grade cleanliness, destination and dangerous-goods requirements. Store in tightly closed compatible containers in a dry, ventilated area away from heat, ignition sources and incompatible materials. High-purity and battery-related grades require particular protection from moisture and contamination.

Frequently Asked Questions

Is CAS 616-38-6 Dimethyl Carbonate?

Yes. CAS 616-38-6 identifies Dimethyl Carbonate, commonly abbreviated DMC.

Is every 99.9% DMC battery grade?

No. Battery grade requires additional low-water, low-acid and trace-impurity controls.

Can DMC replace any solvent directly?

No. Solvency, evaporation, flammability, process compatibility, emissions and product performance must be validated.

Safety note: DMC is flammable. This page provides general B2B information and does not replace the current SDS, process validation or regulatory assessment.
