Diethyl Carbonate (DEC) Supplier in Malaysia
- Also known as
- DEC
- Carbonic Acid Diethyl Ester
- Ethyl Carbonate
Diethyl carbonate (DEC) supplier for battery, formulation and synthesis buyers in Malaysia. This clear, colourless acyclic carbonate ester is also known as carbonic acid diethyl ester and has CAS 105-58-8. Buyers use it as a liquid solvent, an electrolyte component and a process reagent.
The grade decision is application-led. General industrial solvent material is suited to compatible formulation work, while electrolyte and other high-purity duties normally require tighter control of moisture, acidity and trace impurities. Synthesis buyers may instead focus on assay and route-specific impurity limits.
In lithium-ion electrolyte blends, DEC is selected as a low-viscosity co-solvent alongside other carbonate components. It is also used in selected coatings, lacquers and ink systems and as a reagent in organic, fine-chemical and pharmaceutical synthesis. Diethyl carbonate is not interchangeable by name with dimethyl, ethylene or propylene carbonate.

Diethyl Carbonate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Industrial solvent grade | clear, colourless liquid | — | Solvent and formulation input for resin, coating and synthesis processes that specifically call for an acyclic carbonate ester. | Confirm the required pack format with the quotation. |
| High-purity and battery electrolyte grade | clear, colourless liquid | — | Electrolyte co-solvent duty where buyers define water, acidity, assay and other impurity limits for the intended cell chemistry. | Confirm the required pack format with the quotation. |
| Synthesis intermediate grade | clear, colourless liquid | — | Reagent and intermediate for routes that use diethyl carbonate to introduce ethoxycarbonyl or ethyl functionality. | Confirm the required pack format with the quotation. |

Diethyl Carbonate applications
Safety and handling
Keep sealed in a cool, well-ventilated place away from heat, ignition sources and strong oxidisers. Use gloves and eye protection and follow the safety data sheet for the quoted grade.
Common questions about diethyl carbonate
What is diethyl carbonate used for?
Its main commercial roles are as an electrolyte co-solvent, a carbonate solvent in selected formulations, and a reagent in organic synthesis. State the application so the relevant purity and moisture controls can be quoted.
Is diethyl carbonate the same as dimethyl carbonate?
No. Diethyl carbonate, CAS 105-58-8, carries ethyl groups while dimethyl carbonate carries methyl groups, and they are separate chemicals with their own pages. Do not substitute one for the other without checking the formulation.
Is battery-grade diethyl carbonate different from industrial grade?
Battery applications usually call for defined limits on water, acidity and trace impurities that may not be part of a general solvent specification. Send the target specification or required limits with the enquiry.
Which packing formats are available?
Pack format depends on grade, quantity and source. Include the preferred format in the enquiry; available options are confirmed with the quotation.
How do I request a diethyl carbonate price in Malaysia?
Provide the grade, any purity or water limit, quantity, delivery location and preferred packing. Price is issued on enquiry with a stated validity period rather than as a fixed published figure.
What documentation can be provided with a diethyl carbonate quote?
List the documents you need, such as a certificate of analysis or safety data sheet, in the enquiry. Available documentation is confirmed for the quoted grade before supply is arranged.
