Acetonitrile, anhydrous, 99.8+%, Thermo Scientific Chemicals

Description

Water <100ppm, typically 50ppm (0.005%)

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.
