1. Product Description:

  Dimethylformamide (DMF) is a transparent liquid that is miscible with water and most organic solvents. It is a common solvent for chemical reactions. Pure dimethylformamide is odorless, but industrial grade or deteriorated dimethylformamide has a fishy taste because it contains an impurity of dimethylamine. The name comes from the fact that it is a dimethyl substitute for formamide (the amide of formic acid), and both methyl groups are located on the N (nitrogen) atom. Dimethylformamide is a polar (hydrophilic) aprotic solvent with high boiling point, which can promote the SN2 reaction mechanism. Dimethylformamide is made from formic acid and dimethylamine. Dimethylformamide is unstable (especially at high temperatures) in the presence of a strong base such as sodium hydroxide or a strong acid such as hydrochloric or sulfuric acid, and hydrolyzes to formic acid and dimethylamine.
