High Purity 99.9% Min CAS 68-12-2 Dimethylformamide
Dimethyl Formamide/DMF

Dimethylformamide  is an  organic compound  with the  formula  ( CH ₃ ) ₂ NC(O)H. Commonly abbreviated as DMF (although this initialism is sometimes used for  dimethylfuran , or  dimethyl fumarate ), this colourless liquid 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 impurity of  dimethylamine . Dimethylamine degradation impurities can be removed by sparging degraded samples with an inert gas such as  argon  or by sonicating the samples under reduced pressure. As its name indicates, it is a derivative of  formamide , the  amide  of  formic acid . DMF is a  polar  ( hydrophilic )  aprotic solvent  with a high  boiling point . It facilitates reactions that follow polar mechanisms, such as  S _N 2  reactions.

DMF is hydrolyzed by strong acids and bases, especially at elevated temperatures. With sodium hydroxide, DMF converts to formate and dimethylamine. DMF undergoes decarbonylation near its boiling point to give dimethylamine. Distillation is therefore conducted under reduced pressure at lower temperatures.

In one of its main uses in organic synthesis, DMF was a reagent in the Vilsmeier-Haack reaction, which is used to formylate aromatic compounds.The process involves initial conversion of DMF to a chloroiminium ion, [(CH ₃ ) ₂ N=CH(Cl)] ⁺ , known as a Vilsmeier reagent, which attacks arenes.
