Acetonitrile, often abbreviated MeCN (methyl cyanide), is the chemical compound with the formula CH 3 CN and structure H 3 C−C≡N. This colourless liquid is the simplest organic nitrile ( hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic ).
Acetonitrile appears as a colorless limpid liquid with an aromatic odor. Flash point 42 °F. Density 0.783 g / cm3. Toxic by skin absorption. Less dense than water. Vapors are denser than air. Acetonitrile is a nitrile that is hydrogen cyanide in which the hydrogen has been replaced by a methyl group.
