    General description

    Acetonitrile (MeCN), an aliphatic nitrile, is a colorless liquid with a pleasant odor. It is widely used as a solvent and intermediate in organic syntheses.[1] It is transparent to UV-visible light making it highly applicable in spectrophotometric and fluorimetric techniques. As MeCN has low viscosity, high elution strength and is highly miscible in water, it is utilized as a mobile phase component in many chromatographic techniques.[2] Its infrared spectrum has been recorded.[3] Synthesis of alkyl hydroperoxides in MeCN by alkane oxidation with hydrogen peroxide in the presence of iron complexes has been studied.[4] The hydrogenation of MeCN to form ethylamine using Co–B amorphous alloy catalyst has been investigated.[5]
