Dimethylformamide N N-Dimethylformamide Dmf Solvent Cas 68-12-2 For
Dimethylformamide (DMF) is a clear liquid that is miscible with
water and most organic solvents. It is a common solvent for
chemical reactions. Pure dimethylformamide has a special odor, and
industrial grade or deteriorated dimethylformamide has a fishy
smell because it contains impurities of dimethylamine. The name is
derived from the fact that it is a dimethyl substitution of
formamide (an amide of formic acid) and both methyl groups are
located on the N (nitrogen) atom. Dimethylformamide is a high
boiling polar (hydrophilic) aprotic solvent that promotes the SN2
reaction mechanism. Dimethylformamide is made using methyl formate
and dimethylamine. Dimethylformamide is unstable (especially at
elevated temperatures) in the presence of a strong base such as
sodium hydroxide or a strong acid such as hydrochloric acid or
sulfuric acid and hydrolyzed to formic acid and dimethylamine.
HCON(CH3)2+H2O → (CH3)2NH+HCOOH.

Features of DMF Dimethylformamide
DMF is an important organic material and good solvent.
It is used as solvent for man-made leather and chemical fiber;
also used as material for synthesis of insecticide of
high-effectiveness and low-toxicity, as gas absorbent and purity
the gas in petrochemical industry, as material of sulfadiazine,
cortisone and vitamin B6 in pharmaceutical industry;
and also as fixing agent in vapor-phase analysis.
- Dimethylformamide finds wide usage as a solvent with low
- Dimethylformamide is used in the production of plastics incl.
acrylic fibers and polymers
- It is also used as a solvent in pharma sector (peptide coupling),
pesticides industry, and in the manufacture of adhesives, synthetic
leathers, fibers, films, and surface coatings
- It is used as a reagent (eg. Bouveault aldehyde synthesis /
Vilsmeier-Haack reaction), and is useful in the method of forming
- DMF makes most plastics swell, making it very suitable for solid
phase peptide synthesis. It is also used as a component of paint
