  1,2-Dimethoxyethane (CAS NO.110-71-4) is often used as a higher boiling alternative to diethyl ether and THF. As a bidentate ligand, it is used in organometallic chemistry like Grignard reactions, hydride reductions, and palladium-catalyzed reactions like Suzuki reactions and Stille coupling. It is also a good solvent for oligo- and polysaccharides. It is used as the low-viscosity component of the solvent for electrolytes of lithium batteries.
