Description and Uses
off-white to green powder. Insoluble in water,soluble in HCI, Nl40H, and potassium cyanide. Used in Sandmeyer's reaction to synthesize aryl cyanides. Toxic by skin absorption, through open wounds, by ingestion, and by inhalation of hydrogen cyanide that arises from slight decomposition. Produces toxic oxides of nitrogen in fires.
Cuprous cyanide is used in electroplating; as an insecticide and fungicide; and as a catalyst for polymerization.
