Dimethylformamide (DMF)
CAS Number: 68-12-2
Dimethylformamide (DMF, ≥99.9%) is a polar aprotic solvent with excellent solvency for a wide range of organic and inorganic compounds. It is the primary solvent for polyurethane and acrylic fiber spinning, polyimide film casting, pharmaceutical synthesis, and chemical reactions requiring high polarity. Its high boiling point and low volatility enable high-temperature processing.
