Diethylene glycol dimethyl ether (diglyme) is a polar aprotic solvent widely used in lithium battery electrolytes, polymer synthesis, and as a reaction medium for organometallic chemistry. It dissolves a broad range of organic and inorganic compounds while maintaining stability under ambient storage conditions. CAS 111-96-6, molecular formula (CH3OCH2CH2)2O, molecular weight 134.17 g/mol. Classified as Danger under GHS: it is a flammable liquid and vapour (H226), may form explosive peroxides (EUH019), and may damage the unborn child and is suspected of damaging fertility (H360Df). Molekula supplies diethylene glycol dimethyl ether from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
