What Is Acetonitrile and What Is It Used for in the Laboratory? Direct Answer
Acetonitrile is a clear, highly polar organic solvent that laboratories commonly use for chemical analysis, sample preparation, extraction, and chromatography. In analytical laboratories, many users know Acetonitrile as a mobile phase solvent for High Performance Liquid Chromatography, or HPLC.
Because Acetonitrile mixes well with water, has relatively low viscosity, and works well in many chromatographic methods, laboratories use it in research, quality control, pharmaceutical analysis, food testing, environmental testing, and other laboratory applications.
