Applicazioni

KCN is widely applied in organic synthesis for the synthesis of many organic compounds, for example in the synthesis of hydantoins, spiro heterocycles, nitriles, carboxylic acids, cyanohydrins and in von Richter reaction. It is employed in gold mining, electroplating, and as a reagent in protein characterization.
