Diglyme - Wikipedia

OverviewSolventSafetyDiglyme, or bis(2-methoxyethyl) ether, is a solvent with a high boiling point. It is an organic compound which is the dimethyl ether of diethylene glycol. (The name "diglyme" is a portmanteau of "diglycol methyl ether.") It is a colorless liquid with a slight ether-like odor. It is miscible with water as well as organic solvents. It is prepared by a reaction of dimethyl ether and ethylene oxide over an acid alyst. Wikipedia · CC-BY-SA 许可下的文字

Diglyme | C6H14O3 - PubChem

 · Diglyme metabolism proceeds primarily through an O-demethylation pathway, followed by oxidation to (2-methoxyethoxy)acetic acid. The lack of toxicity of 2-(2-methoxyethoxy)ethanol and (2-methoxyethoxy)acetic acid suggests that the testicular toxicity of diglyme may be due to methoxyacetic acid, a minor metabolite.
