The Acetonitrile, with the register number 75-05-8, is a kind of colorless transparent liquid. Acetonitrile is the chemical compound with the formula CH3CN. It also can be called Cyanomethane and Methyl cyanide . It is produced mainly as a byproduct of acrylonitrile manufacture, and can also be produced by many other methods, but these are of no commercial importance as of 2002. Starting in October 2008, the worldwide supply of Acetonitrile was low because Chinese production was shut down for the Olympics. In inorganic chemistry, acetonitrile is employed as a solvent and often an easily displaceable ligand. It has only a modest toxicity, but it can be metabolised to produce hydrogen cyanide (see below), which is the source of the observed toxic effects. In common with other nitriles, acetonitrile can be metabolised in microsomes, especially in the liver, to produce hydrogen cyanide, as was first shown by Pozzani et al.

Uses of Acetonitrile: Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. It is widely used in battery applications because of its relatively high dielectric constant and ability to dissolve electrolytes. For similar reasons it is a popular solvent in cyclic voltammetry.Industrially, it is used as a solvent for the manufacture of pharmaceuticals and photographic film.
When you are using this chemical, please be cautious about it as the following:
1. Keep away from sources of ignition - No smoking;
2. Wear suitable protective clothing and gloves;
3. In case of accident or if you feel unwell, seek medical advice immediately (show label where possible);
4. Wear suitable protective clothing, gloves and eye/face protection;
5. Take off immediately all contaminated clothing;
6. Wear suitable protective clothing;
