What Is Acetonitrile (CAS 75-05-8) ?

Acetonitrile is a clear, colorless liquid with a mildly sweet odor. It has lower density than water and vapors that are more dense than water vapor. As the name suggests, acetonitrile is a nitrile, also known as an organic cyanide. It also goes by the name methyl cyanide. That means it has a methyl group (―CH3) bonded to a cyano group (―C ≡ N).
