Dimethylformamide or N,N-dimethylformamide is an organic compound with the formula (CH3)2NC(O)H.
DMF penetrates most types of plastic and causes them to swell.
Dimethylformamide is an odorless, colorless liquid, miscible with water and most organic liquids. Technical grade or degraded samples often have a fishy smell due to impurities, such as dimethylamine.
DMF is sold by various chemical suppliers.
- Acyl halide synthesis
- Make cadaverine
DMF has been linked to cancer in humans, and it is thought to cause birth defects.
In closed bottles, away from any acidic vapors. DMF will slowly break down to release dimethylamine.
DMF should be mixed with a more flammable solvent and safely burned.
