| 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). |
| Features and Benefits: | ACS solvents meet or exceed the high standards of the American Chemical Society (ACS) ,with test specifications that are specialized to every compound. According to the American Chemical Society, ACS reagent grade implies that it is a substance of sufficient purity to be used in most chemical analyses or reactions. |
| 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. |
