1,2-Dimethoxyethane, 99+%, stab. with BHT, Thermo Scientific Chemicals

Description

1,2-Dimethoxyethane is widely used as a solvent for electrolyte of lithium batteries, polysilicones, oligo- and polysaccharides. It plays an important role in Grignard reactions, Suzuki reactions and Stille couplings in organometallic chemistry and in pharmaceutical synthesis. It is a higher boiling point solvent and is used as an alternative to diethyl ether and tetrahydrofuran. It is used for the etching of synthetic polymers like polytetrafluoroethylene and other fluoropolymers with alkali metal dispersions.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
