Acetonitrile, often abbreviated MeCN ( methyl cyanide ), is the chemical compound with the formula CHCN and structure HC−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 ). It is produced mainly as a byproduct of acrylonitrile manufacture.
