Copper(I) cyanide (CuCN), also copper cyanide, cuprous cyanide, or cupricin 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.
