An Acetonitrile is a nitrile in which the hydrogen has been replaced by a methyl group in hydrogen cyanide. As an aprotic polar solvent, it inhibits EC 3.5.1.4 (amidase). It is a volatile organic compound composed of aliphatic nitriles. The liquid acetonitrile has an aromatic odor and is colorless...
