Ethyl Methyl Carbonate Supplier in Malaysia
- Also known as
- EMC
- Carbonic Acid Ethyl Methyl Ester
- Methyl Ethyl Carbonate
Ethyl methyl carbonate supplier for battery and electronics buyers in Malaysia. Known across the electrolyte trade by its abbreviation EMC, this low-viscosity carbonate is identified by CAS 623-53-0 and formula C4H8O3, the mixed methyl and ethyl ester of carbonic acid.
Commercial material is a clear, colourless, low-viscosity liquid supplied in battery and high-purity grades. The decisive specification points for most buyers are assay, water content and acidity, which are verified against the required grade rather than assumed from this page.
EMC is used above all as a co-solvent in lithium-ion battery electrolytes, where its low viscosity helps ionic transport, improves electrode wetting and extends the low-temperature window of the blend. It is also a high-purity solvent and carbonate intermediate in specialty and research chemistry.
Send the required grade, target water content, quantity, packing preference and delivery location with your enquiry. Availability, packing, documentation and timing are confirmed in the quotation.

Safety and handling
Keep sealed in a cool, dry place away from ignition sources and moisture. Supply is subject to applicable requirements.
Common questions about ethyl methyl carbonate
What is ethyl methyl carbonate used for?
It is a low-viscosity co-solvent in lithium-ion battery electrolytes. When blended with cyclic carbonates such as ethylene carbonate, EMC lowers the overall viscosity and improves low-temperature performance and wetting.
What does EMC stand for on this page?
EMC is the common abbreviation for ethyl methyl carbonate, CAS 623-53-0. On site search it resolves to this product, not to other uses of the same initialism.
Which grade should I request?
Battery electrolyte work usually specifies battery-grade material with tight water and acid control. Give your target limits for moisture and assay so the grade can be matched to your specification.
How is ethyl methyl carbonate packed?
It is a liquid, so commercial supply commonly uses sealed drums, IBCs or purpose-built containers that keep moisture out. Confirm the preferred pack and volume with the quotation.
What details are needed for a price enquiry?
Provide the grade, target water content, quantity, preferred pack and delivery location. The material is quoted on enquiry with a stated validity period.
