Dimethylformamide, abbreviated as DMF，is a colorless, transparent, high-boiling-point liquid with a faint amine odor. Molecular Formula: C₃H₇NO MW: 73.09. It is a compound formed by replacing the hydroxyl group of formic acid with a dimethylamino group. As a highly polar, high-boiling-point non-protonic organic solvent, it possesses exceptional dissolving power and is hailed as the “universal solvent.”
