Diethylene Glycol Dimethyl Ether, commonly known as DEDM or Diglyme (bis(2-methoxyethyl) ether), is an aprotic polar solvent with the molecular formula C6H14O3 and CAS number 111-96-6. Its EINECS number is 203-924-4. As a glycol ether derivative, DEDM features two ether linkages and two terminal methyl groups, which contribute to its solvency across a wide range of organic and inorganic substances.
DEDM is classified as an aprotic solvent because it lacks an acidic proton on its oxygen atoms, making it suitable for reactions involving strong bases or reactive organometallic reagents. Its polar nature allows it to dissolve many salts and polar organic compounds, while its ether structure provides compatibility with non-polar materials. This dual solubility profile makes DEDM a versatile choice for industrial clients seeking a single solvent for multi-component formulations.

DEDM serves as a solvent for various organic reactions, including anionic polymerization, condensation reactions, and Grignard reagent preparation. Its aprotic nature and ability to solvate cations make it suitable for reactions involving organometallic compounds. Commercial users in the pharmaceutical and specialty chemical sectors use DEDM as a reaction medium where precise control over reaction kinetics is required.
In adhesive manufacturing, DEDM functions as a co-solvent and viscosity modifier. It enhances the solubility of resin components and improves film formation during curing. Business buyers in the adhesives industry incorporate DEDM into formulations for epoxy, polyurethane, and acrylic-based adhesive systems.
DEDM acts as an ingredient in industrial cleaning formulations, where its solvency power supports the removal of oils, greases, and organic residues. Its moderate evaporation rate allows sufficient contact time for effective cleaning without prolonged residue. Enterprise customers in the electronics and precision manufacturing sectors use DEDM-based cleaners for component degreasing.
Due to its ability to dissolve lithium salts and its wide liquid temperature range, DEDM finds use as a co-solvent in certain electrolyte formulations. Its dielectric properties support ion mobility in specialized battery systems.
DEDM is available in multiple packaging options to suit different commercial procurement scales: 200 kg iron drums, 1000 L IBC totes, and ISO tank containers for bulk shipments. The minimum order quantity is 1 metric ton.
Storage requires a cool, well-ventilated area away from oxidizing agents and open flames. Containers should remain sealed when not in use. The recommended storage temperature is below 30°C. Personnel handling DEDM should wear appropriate PPE, including chemical-resistant gloves and safety glasses, per the MSDS guidelines.
Industrial-grade DEDM is produced with a minimum purity of 99%, verified by gas chromatography. Each batch accompanies a Certificate of Analysis (COA) detailing purity, water content, acidity, and color (APHA). The product conforms to standard industrial chemical specifications. For specialized applications requiring higher purity grades, customized specifications can be discussed with the technical team.
The minimum order quantity for industrial-grade DEDM is 1 metric ton. Smaller sample quantities may be available for evaluation purposes upon request.
Standard lead time is 7 - 15 working days from order confirmation, depending on order volume and packaging requirements. Bulk shipments via ISO tank may require additional scheduling time.
DEDM is generally compatible with HDPE and PTFE materials. Compatibility testing is recommended for long-term storage in specific polymer containers. Detailed compatibility data is available in the MSDS.
DEDM is REACH registered for supply within the European Union. Relevant registration details can be provided upon request for commercial users requiring compliance documentation.
When stored in original sealed containers under recommended conditions, DEDM has a shelf life of 24 months from the date of manufacture. Periodic quality checks are advised for extended storage.
Industrial-grade DEDM (≥ 99% purity) is intended for general industrial use. Pharmaceutical or high-purity grades require additional purification steps and should be specified separately during the procurement process.
