China Cas 111-87-5 Dimethylformamide (DMF) CAS 68-12-2 China Best Price – Chemwin Detail:

Product Name：N,N-Dimethylformamide

Molecular format：C3H7NO

CAS No：68-12-2

Product molecular structure：

Chemical Properties:

N,N-Dimethylformamide is a colorless or slightly yellow liquid with a boiling point of 153°C and a vapor pressure of 380 Pa at 20°C. It is freely soluble in water and soluble in alcohols, acetone and benzene. N,N-Dimethylformamide is used as solvent, catalyst and gas absorbent. React violently with concentrated sulfuric acid, fuming nitric acid and can even explode. Pure Dimethylformamide is odorless, but industrial grade or modified Dimethylformamide has a fishy smell because it contains impurities of 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 acid or sulfuric acid, and is hydrolyzed to formic acid and dimethylamine.

Application:

N,N-Dimethylformamide (DMF) is a clear liquid that has been widely used in industries as a solvent, an additive, or an intermediate because of its extensive miscibility with water and most common organic solvents.

Dimethylformamide is primarily used as an industrial solvent. Dimethylformamide solutions are used toprocess polymer fibers, films, and surface coatings; to permit easy spinning of acrylic fibers; to produce wire enamels, and as a crystallization medium in the pharmaceutical industry.

DMF can also be used for formylation with alkyllithium or Grignard reagents.

It is used as a reagent in Bouveault aldehyde synthesis and also in Vilsmeier-Haack reaction. It acts as a catalyst in the synthesis of acyl chlorides. It is used for separating and refining crude from olefin gas. DMF along with methylene chloride acts as a remover of varnish or lacquers. It is also used in the manufacture of adhesives, fibers and films.

N,N-Dimethylformamide (DMF) is a solvent with a low evaporation rate, useful for preparing solutions with a variety of hydrophobic organic compounds used in molecular biology applications.

N,N-Dimethylformamide was used to solubilize MTT crystals in cell viability assays.It was also used in feruloyl esterase activity assay in molds exhibiting high activity of the enzyme.

The world-wide consumption of DMF in 2001 was approximately 285, 000 metric tonnes and most of that was used as an industrial solvent.
