Acetonitrile, an aliphatic nitrile, is a highly volatile, aprotic polar organic solvent that finds wide use in analytical determinations. It is UV-transparent - a property that facilitates its utilization in spectrophotometric and fluorimetric analyses. Its low viscosity, high elution strength and miscibility in water makes it viable in many chromatography systems. Its other applications include its use as a mobile phase additive and as an extraction solvent in liquid-liquid extraction (LLC), solid-phase extraction (SPE) and microextraction for chromatographic applications, etc.
