Copper(I) cyanide

Copper(I) cyanide (CuCN), also copper cyanide, cuprous cyanide, or cupricin (CAS number [544-92-3], EINECS number 208-883-6) is a white to cream colored or sometimes greenish powdery solid that is insoluble in water. Its chemical formula is CuCN. It is a poison that reacts violently with magnesium. When heated to decomposition, it emits very toxic fumes containing hydrogen cyanide, but it is not flammable itself.

Cuprous cyanide was used as a catalyst in polymerizations, in electroplating of copper and iron, and as insecticide, fungicide, and biocide in marine paints.

Its risk and safety phrases are R26/27/28 R32 R50/53 (S1/2) S7 S24/25 S26 S28 S29 S45 S60 S61.
