Its ultraviolet transparency UV cutoff , low viscosity and low chemical reactivity make it a popular choice for high-performance liquid chromatography HPLC.

Acetonitrile plays a significant role as the dominant solvent used in the manufacture of DNA oligonucleotides from monomers. Industrially, it is used as a solvent for the manufacture of pharmaceuticals and photographic film.

Acetonitrile is a ligand in many transition metal nitrile complexes. Being weakly basic, it is an easily displaceable ligand.

For example, bis acetonitrile palladium dichloride is prepared by heating a suspension of palladium chloride in acetonitrile: [12].

The CH 3 CN groups in these complexes are rapidly displaced by many other ligands. Acetonitrile is a byproduct from the manufacture of acrylonitrile.

Most is combusted to support the intended process but an estimated several thousand tons are retained for the above-mentioned applications.

Acetonitrile can also be produced by many other methods, but these are of no commercial importance as of Illustrative routes are by dehydration of acetamide or by hydrogenation of mixtures of carbon monoxide and ammonia.

Catalytic ammoxidation of ethylene was also researched. Starting in October , the worldwide supply of acetonitrile was low because Chinese production was shut down for the Olympics.

Furthermore, a U. Acetonitrile is a byproduct in the production of acrylonitrile and its production also decreased, further compounding the acetonitrile shortage.

Acetonitrile has only modest toxicity in small doses. Cases of acetonitrile poisoning in humans or, to be more specific, of cyanide poisoning after exposure to acetonitrile are rare but not unknown, by inhalation, ingestion and possibly by skin absorption.

Convulsions and coma can occur in serious cases, followed by death from respiratory failure. The treatment is as for cyanide poisoning , with oxygen , sodium nitrite , and sodium thiosulfate among the most commonly used emergency treatments.

It has been used in formulations for nail polish remover , despite its toxicity. At least two cases have been reported of accidental poisoning of young children by acetonitrile-based nail polish remover, one of which was fatal.

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.

The glycolonitrile then undergoes a spontaneous decomposition to give hydrogen cyanide and formaldehyde.

The metabolism of acetonitrile is much slower than that of other nitriles, which accounts for its relatively low toxicity.

The relatively slow metabolism of acetonitrile to hydrogen cyanide allows more of the cyanide produced to be detoxified within the body to thiocyanate the rhodanese pathway.

It also allows more of the acetonitrile to be excreted unchanged before it is metabolised.

The main pathways of excretion are by exhalation and in the urine. From Wikipedia, the free encyclopedia. Not to be confused with Acetyl cyanide.
