Description
Diglyme (CAS 111-96-6) is an ether-based solvent also known as Glyme 2, Dimethyl Carbitol, Dimethyl Digol, and Dimethyldiglycol. It carries no assigned E-code and is identified under EC 203-924-4. It is commercially supplied as a high-purity aprotic solvent with strong solvating power for ionic species and polar compounds.
In polymer and resin formulations, Diglyme functions as a reactive diluent and crosslinking co-agent, improving cure uniformity in epoxy systems. In pharmaceutical manufacturing, it serves as a reaction solvent and catalyst carrier, stabilising sensitive intermediates during synthesis. Its humectant behaviour also supports moisture retention in biotechnology process media.
Diglyme is available in technical and high-purity grades, with REACH compliance confirmed under EU chemical regulations. It is supplied in standard drum and IBC formats suited to industrial procurement volumes. Buyers should verify grade suitability against Ph.Eur. or internal specification requirements prior to formulation use.
