Acetonitrile is the simplest organic nitrile. It is produced mainly as a byproduct of acrylonitrile manufacture. It is mainly used as a polar aprotic solvent in purification of butadiene. In the laboratory, it is used as a medium-polarity solvent that is miscible with water and has a convenient liquid range. It is widely used in battery applications because of its relatively high dielectric constant and ability to dissolve electrolytes. For similar reasons it is a popular solvent in cyclic voltammetry. Its low viscosity and low chemical reactivity make it a popular choice for liquid chromatography. Acetonitrile plays a significant role as the dominant solvent used in the manufacture of DNA oligonucleotides from monomers. Industrially, it is used as a solvent for the manufacture of pharmaceuticals and photographic film.
