Diglyme

We provide diglyme, or bis (2-methoxyethyl) ether, that is a solvent with high boiling point. The name "diglyme" is a portmanteau of diglycol methyl ether. It is an organic compound that is the dimethyl ether of diethylene glycol. It is a clear, colorless liquid with a slight ether-like odor. It is miscible with water, alcohols, diethyl ether, and hydrocarbon solvents. It is mainly used as a solvent in organic reactions. It has the ability to chelate small cations, leaving anions more active. Therefore, reactions involving organometallic reagents, such as grignard reactions or metal hydride reductions, may have significantly enhanced reaction rates.

A lithium cation being chelated by a diglyme molecule diglyme is also used as a solvent in hydroboration reactions with diborane. Its stability, even at high pH values, makes it an excellent solvent for reactions with strong bases or reactions that require high temperatures.
