General description

1,2-Dimethoxyethane is a water miscible solvent, used as an alternative for the hazardous organic solvents such as dioxane and tetrahydrofuran.
This compound is listed in the SVHC (Substances of very high concern) candidate list of ECHA (European Chemicals Agency)

Application

1,2-Dimethoxyethane may be used as a solvent for the separation and determination of neutral sugars as 2,4- dinitrophenyl derivatives using high-performance liquid chromatography.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
