Description

A clear, toxic liquid that is considered a universal Solvent since it is miscible in both water and organic solvents. Dimethylformamide (DMF) dissolves most natural and synthetic resins, and, with heat and time, DMF will even soften Epoxy. It is often used in liquid chromatographic systems as a gradient intermediate between polar and nonpolar solvents. DMF is also used in some commercial paint stripping formulations.
