Diethylene glycol dimethyl ether

Diethylene glycol dimethyl ether (CAS 111-96-6), commercially known as Diglyme, is a high-boiling aprotic ether solvent used across pharmaceutical synthesis and polymer processing. Its controlled evaporation rate and strong solvating power make it a preferred solvent where lower-boiling alternatives fail to maintain process stability during specialty chemical manufacturing.

In pharmaceutical manufacturing, Diglyme functions as a reaction solvent for Grignard reactions, metal hydride reductions, and other moisture-sensitive syntheses requiring an inert, coordinating medium. Polymer formulators use it as a polymerization solvent and chain-transfer agent in the production of specialty resins and adhesives for industrial applications.

In battery electrolyte research and lithium-ion cell development, it serves as a co-solvent that improves ionic conductivity and electrode compatibility for advanced energy storage. Biotechnology applications include its use as a carrier solvent in reagent formulations where consistent solvation and low reactivity with biological substrates are required.

Diglyme is supplied as a clear liquid in drum, IBC, and bulk quantities. Technical grade is the standard offering for industrial and research applications across the global market. Anhydrous and high-purity grades are available to meet pharmaceutical and battery-grade specifications. Packaging options typically range from laboratory-scale containers to full bulk tanker supply.
