Beschreibung

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.

Our premium ACS solvents are ideal for routine chemical synthesis, drying, purification, and critical labware cleaning. They meet or exceed the rigorous standards of the American Chemical Society (ACS), ensuring high-quality results for your research needs.
