Calcium cyanamide is produced from calcium carbide and nitrogen gas by an exothermic solid nitrogenation at 1000°C. It is used as a slow release nitrogen fertilizer with beneficial side effects against soilborne deseases. In chemical industry, it is the base for cyanamide and thiourea chemistry.

Cyanamide is a fairly stable, toxic substance obtained from calcium cyanamide by reaction with water and carbon dioxide. It has vast applications in industrial nitrogen organic chemistry, and is also directly used as a plant protection agent.

Dicyandiamide is derived from cyanamide by dimerization in presence of alkali. The nontoxic compound has found widespread industrial applications in resins, plastics, water treatment, and pharmaceuticals.
