Description

General description

Acetonitrile (MeCN), an aliphatic nitrile, is a colorless liquid with a characteristic odor. MeCN has low viscosity, high elution strength and is highly miscible in water. It is widely used as a solvent and intermediate in organic syntheses and is transparent to UV-visible light, making it highly applicable in spectrophotometric and fluorimetric techniques. It also plays a major role as an extractant medium in liquid-liquid extraction, solid-phase extraction or microextraction.

Application

Acetonitrile may be used as solvent in the following processes:

Organic synthesis
Liquid-liquid extraction, solid-phase extraction or microextraction.
Spectrophotometric and fluorimetric techniques.
Electrolytes in lithium-ion batteries
Determination of pKa values of organic superbases using the isodensity polarization continuum model (IPCM).
