Preparation: KOCN is prepared by urea with potassium carbonate at 400 °C. The reaction produces a liquid. Intermediates and impurities include biuret, cyanuric acid, and potassium allophanate (KO₂CNHC(O)NH₂), as well as unreacted starting urea, but these species are unstable at 400 °C.

2 OC(NH2)₂ + K₂CO₃ → 2 KOCN + (NH₄)₂CO₃

Uses of Potassium cyanate: The product is used as a basic raw material for various organic syntheses, for example, urea derivatives, semicarbazides, carbamates and isocyanates. It is also used for the heat treatment of metals. This reagent is used to prepare herbicide.
