CAS 75-05-8: Acetonitrile

Acetonitrile is utilized as a polar aprotic solvent in organic synthesis and in the purification of butadiene. Aqueous two-phase systems based on acetonitrile and carbohydrates play an important character in the extraction and purification of biomolecules called vanillins. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Acetonitrile is utilized as a polar aprotic solvent in organic synthesis, and in the purification of butadiene. It is used in all the analytical laboratories as a major component of mobile phase in High Performance Liquid Chromatography (HPLC) and in Liquid Chromatography - Mass Spectrometry (LC-MS). It is used for the extraction of fatty acids, spinning fibers and casting and molding of plastic materials. Aqueous two-phase systems based on acetonitrile and carbohydrates play an important character in the extraction and purification of biomolecules called vanillins. It acts as a stabilizer for the chlorinated solvents, and finds use in the production of DNA oligonucleotides.
