Description
A clear, poisonous liquid with an ether-like odor. Acetonitrile is produced as a byproduct in the formation of acrylonitrile polymers. It is a highly polar solvent that is miscible with a large number of solvents making it very useful for gradient changes in the polarity of eluent systems for liquid chromatography. Acetonitrile is also used to separate fatty acids from vegetable oils and is used in the manufacturing of synthetic pharmaceuticals.
Synonyms and Related Terms
methyl cyanide; cyanomethane; ethane nitrile
