Cyanoguanidine is an nitrile derived from guanidine. It is a dimer of cyanamide, from which it can be prepared. Cyanoguanidine is a colourless solid that is soluble in water, acetone, and alcohol, but not indiethyl ether or chloroform.
Cyanoguanidine is produced by treating cyanamide with base. It is produced in soil by decomposition of cyanamide. A variety of useful compounds are produced from cyanoguanidine, guanidines and melamine.
It is also used as a slow fertilizer. Formerly, it was as a fuel in some explosives. It is used in the adhesive industry as a curing agent for epoxies.
It is possible to draw a tautomer of cyanoguanidine with the structure NC-NH-C(NH)NH2. Further tautomerization gives NC-NH-C(N-)NH3+. Formal loss of neutral ammonia (NH3) from this latter tautomer followed by deprotonation gives the anion commonly referred to the dicyanamide ion, (NC)2N-. The dicyanamide ion has been used extensively as a counterion in the chemistry of organic and inorganic salts, for example in the synthesis of what was, in 1990, a superconductor with novel properties where we can see the anion depicted as N(CN)2-.
Dicyandiamide in Fertilizers
Dicyandiamide is used in fertilizer formulations as a slow/continuous release nitrogen source. There are two major ways in which nitrogen is lost from soil - denitrification and leeching. Denitrification is loss of nitrogen to the atmosphere. Leeching is when nitrogen is washed from soil through rain or irrigation. Dicy has been shown to prevent nitrogen loss through both leeching and de-nitrification in soil. This helps reduce the negative effects of greenhouse gas emission such as nitrous oxide and nitrate leaching into waterways. A study illustrating the positive effects of Dicyandiamide in agricultural industries and the denitrification process across various types of soils and variable concentrations such as urea and bovine urine
