Useful:

• Chemical Classes: Solvents -> Amides (
• Canonical SMILES: CN(C)C=O
• Inhalation Risk: A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20 °C.
• Effects of Short Term Exposure: The substance is irritating to the eyes and respiratory tract. The substance may cause effects on the liver. This may result in tissue lesions. The effects may be delayed. Medical observation is indicated. If swallowed the substance easily enters the airways and could result in aspiration pneumonitis.
• Effects of Long Term Exposure: The substance may have effects on the liver. This may result in impaired functions. Tumours have been detected in experimental animals but may not be relevant to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
• Physical properties: Clear, colorless to light yellow, hygroscopic, mobile liquid with a faint, characteristic, ammonialike odor. An experimentally determined odor threshold concentration of 100 ppmv was reported by Leonardos et al. (1969).
• Uses: 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 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.
