Dimethylformamide, DMF is an organic compound with the chemical formula H C O N(CH 3) 2. Its structure is HC(=O)−N( −CH 3 ) 2 . 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.

The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
Molar mass: 101.149 g·mol −1 Appearance colorless liquid ... It is used in place of the related dimethylformamide for niche applications. Preparation
N-Methylformamide (NMF) is a colorless, nearly odorless, organic compound and secondary amide with molecular formula CH 3 NHCHO, which is a liquid at room temperature. NMF is mainly used as a reagent in various organic syntheses with limited applications as a highly polar solvent.
Deuterated dimethylformamide ((CD 3) 2 NCOD), also known as deuterated DMF, is an isotopologue of DMF ((CH 3) 2 NCOH) in which the hydrogen atom ("H") is replaced with a deuterium isotope ("D"). Deuterated DMF is a relatively uncommon solvent used in NMR spectroscopy .

It is generated by protonation of (CH 3) 3 COCH(N(CH 3) 2) 2 (Bredereck's reagent). [3](CH 3) 3 COCH(N(CH 3) 2) 2 + H + → (CH 3) 3 COH + [CH(N(CH 3) 2) 2] +. N,N,N′,N′-Tetramethylformamidinium chloride is also obtained in high yield (95%) in the reaction of dimethylformamide (DMF) with dimethylcarbamoyl chloride [4] The conversion of DMF with thionyl chloride in a ratio of 3:1 obtains ...
