 Benzoyl cyanide (613-90-1) also can be called for alpha-Oxobenzeneacetonitrile ; .alpha.-Oxobenzeneacetonitrile ; Glyoxylonitrile, phenyl- ; benzeneacetonitrile, alpha-oxo- ; Benzeneacetonitrile, .alpha.-oxo- ; Oxo(phenyl)acetonitrile .It can be used as intermediates of herbicide Metamitron and organic synthesis, and, can be derived by the reaction of benzoyl chloride with cuprous cyanide .
 Benzoyl cyanide (613-90-1) is hazardous,so the first aid measures and others should be known.Such as: When on the skin: first,should  flush skin with plenty of water immediatelyfor at least 15 minutes while removing contaminated clothing. Secondly,Get shoesmedical aid . Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.Then get medical aid soon.While ,it's Inhaled: Remove from exposure and move to fresh air immediately.Give artificial respiration while not breathing. When breathing is difficult, give oxygen.And as soon as to get medical aid.Then you have the ingesting of the product : Wash mouth out with water,and get medical aid immediately.Notes to physician: Treat supportively and symptomatically.
In addition, Benzoyl cyanide (613-90-1) can be stable under normal temperature and pressure conditions.It is not compatible with strong oxidizing agents,ignition sources, and you must not take it with strong reducing agents, strong oxidizing agents, strong bases, strong acids.And it should not be exposured to moist air or water.And also prevent it to broken down into hazardous decomposition products: cyanide fumes, nitriles,carbon dioxide,carbon monoxide,nitrogen oxides.
