Acetonitrile is a clear, colorless, highly polar organic solvent widely used in HPLC, GC-MS, and peptide synthesis due to its excellent solvency and low UV cutoff. It is also employed in electrochemical applications and as a reaction medium in chemical synthesis. On an industrial scale, it serves as a process solvent in pharmaceutical manufacturing and butadiene extraction, and as a starting material for amines, amides and nitrogen heterocycles. This product has a CAS number of 75-05-8, with the molecular formula CH3CN and a molecular weight of 41.05 g/mol. It is stored at ambient conditions and carries a Danger signal word for hazards including flammability and toxicity. Molekula supplies acetonitrile from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
