2-Cyanoguanidine or commonly dicyandiamide is an amine derived from guanidine. It is a dimer of cyanamide, from which it can be prepared. 2-Cyanoguanidine is soluble in water, acetone, and alcohol, but not in diethyl ether or chloroform.
2-Cyanoguanidine is produced in soil by decomposition of cyanamide.
Uses
2-Cyanoguanidine is an intermediate in the synthesis of melamine and other organic chemicals. It is also used as a slow fertilizer. Formerly, it was used together with strong oxidizing agents as an explosive.
