Is dmf a solvent
WebDimethylformamide (DMF) is a colorless, water-soluble liquid with a faint ammonia-like odor. This organic solvent is used in acrylic fiber spinning, chemical manufacturing, and pharmaceutical production; it is also present in textile dyes and pigments, paint stripping solvents, and coating, printing, and adhesive formulations [NIOSH/OSHA 1981]. WebAug 3, 2024 · In the present review, we will reveal that DMF is actually something much more than a solvent. It is a unique chemical since, as well as being an effective polar aprotic solvent, it can play three other important roles in organic chemistry. It can be used as a reagent, a catalyst, and a stabilizer.
