Acetonitrile
Acetonitrile is the chemical compound with the formula CH3CN. 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. It is used as a polar aprotic solvent in organic synthesis and in the purification of butadiene.
