CAS 75-05-8: Acetonitrile

Description: Acetonitrile, with the chemical formula CH₃CN and CAS number 75-05-8, is a colorless, volatile liquid that is widely used as a solvent in various chemical processes. It has a distinctive sweet odor and is highly polar, which makes it an excellent solvent for a range of organic compounds, particularly in reactions involving nucleophiles. Acetonitrile has a relatively low boiling point and high dielectric constant, contributing to its effectiveness in dissolving salts and other polar substances. It is miscible with water and many organic solvents, enhancing its utility in laboratory and industrial applications. Acetonitrile is also used in the production of pharmaceuticals, as well as in the extraction of certain compounds and in chromatographic techniques. While it is generally considered to have low toxicity, exposure can lead to irritation of the skin, eyes, and respiratory system, necessitating appropriate safety measures when handling. Its chemical stability and reactivity make it a valuable compound in organic synthesis and analytical chemistry.
