| N,N-Dimethylformamide Usage And Synthesis |
| Chemical Properties | Clear colorless liquid |
| Usage | Solvent for many hydrophobic organic compounds. |
| General Description | A water-white liquid with a faint fishy odor. Flash point 136 °F. Slightly less dense than water. Vapors heavier than air. Toxic by inhalation or skin absorption. May irritate eyes. |
| Air & Water Reactions | Flammable. Water soluble. |
| Reactivity Profile | N,N-Dimethylformamide may react violently with a broad range of chemicals, e.g.: alkaline metals (sodium, potassium), azides, hydrides (sodium borohydride, lithium aluminum hydride), bromine, chlorine, carbon tetrachloride, hexachlorocyclohexane, phosphorus pentaoxide, triethylaluminum, magnesium nitrate, organic nitrates. Forms explosive mixtures with lithium azide [Bretherick, 5th ed., 1995, p. 453]. Oxidation by chromium trioxide or potassium permanganate may lead to explosion [Pal B. C. et al., Chem. Eng. News, 1981, 59, p. 47]. |
| Health Hazard | Irritation of eyes, skin and nose. May cause nausea. |
| Fire Hazard | Special Hazards of Combustion Products: Vapors are irritating |
