Acetonitrile CH3CN - PubChem
WebAcetonitrile has an odor threshold of 170 ppm. (9) Acetonitrile is very soluble in water and is quite flammable. (9) The chemical formula for acetonitrile is C 2 H 3 N, and the molecular … Acetonitrile, often abbreviated MeCN (methyl cyanide), is the chemical compound with the formula CH3CN and structure H3C−C≡N. This colourless liquid is the simplest organic nitrile (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic). It is produced mainly as a byproduct of acrylonitrile manufacture. It is used as a polar aprotic solvent in organic synthesis and in the purification of butadiene. The N≡C−C skeleton is linear with a short C≡N distance of 1.16 WebAug 17, 2010 · pH value is the best known parameter for characterizing acidity of a solution.
