DMF is an organic compound with the formula (CH3)2NC(O)H, which is a colorless liquid that is miscible with water and most organic liquids. Dimethylformamide is miscible with water and the majority of organic liquids. DMF is a common solvent for chemical reactions. Dimethylformamide is odorless, but technical-grade or degraded samples often have a fishy smell due to the impurity of dimethylamine.

Volatile, colorless liquid with a sharp musty odor like rubbing alcohol. Vapors are heavier than air and mildly irritating to the eyes, nose, and throat. Sold in 70% aqueous solution as rubbing alcohol.
