Function&Application
Acetonitrile is the chemical compound with formula CH3CN. This colourless liquid is the simplest organic nitrile. 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.[2]In the laboratory, it is used as a medium-polarity solvent that is miscible with water and has a convenient liquid range. With a dipole moment of 3.84 D, acetonitrile dissolves a wide range of ionic and nonpolar compounds (e.g. Wohl-Ziegler reaction) and is useful as a mobile se in HPLC and LCMS.
