Dicyandiamide is used in the production of wide range of organic chemicals including slowly and continuous nitrogen release fertilisers; fire proofing agent; epoxy laminates for circuit boards, powder coatings and adhesives; water treatment chemicals; dye fixing, leather and rubber chemicals; explosives; pharmaceuticals;

Cyanamide, the amide of normal cyanic acid, is a white crystals melting at 45 C; readily soluble in water, alcohol and ether. It is prepared by the desulphurization of thiourea in the presence of catalyst (mercuric oxide) or by the action of ammonia with cyanogen halides. It polymerizes to dicyandiamide when heated over 150 C and to tricyantriamide as well as to melamine. Its metal salt especially calcium cyanamide is an environmentally friendly multi-purpose fertilizer to supply nitrogen and lime to plants and soil. Cyanamide is used in fertilizer, defoliant and weed killer. It is used as a raw material of melamine, dicyandiamine, thioureas and other guanidines.
