dicyanodiamide

Dicyanodiamide, also known as cyanoguanidine, is an organic compound with the formula C2H4N4. It is a dimer of cyanamide and is a white crystalline solid. It is soluble in water and polar organic solvents. Dicyanodiamide is synthesized by the dimerization of cyanamide under basic conditions.

The compound has several industrial applications. It is used as a precursor in the synthesis of guanidine salts, which are used in pharmaceuticals and as flame retardants. Dicyanodiamide is also employed as a curing agent for epoxy resins, contributing to their strength and durability. In agriculture, it acts as a nitrification inhibitor, slowing the conversion of ammonium to nitrate in soil, thereby improving nitrogen fertilizer efficiency.

In organic synthesis, dicyanodiamide serves as a reagent for the preparation of various heterocyclic compounds. It is a component in some slow-release fertilizers and in certain types of adhesives. Its relatively low toxicity and cost-effectiveness make it a versatile chemical intermediate. Dicyanodiamide can be found in various consumer products, including certain inks and coatings. It is a stable compound under normal storage conditions.
