Guanidine Uses
Guanidine (CAS NO.113-00-8) is used in the manufacture of plastics and explosives and as intermediate in organic synthesis. Is mainly used for manufacture of sulfa drugs and dyes. Because of free guanidine difficult to be separated, so general merchandise is its salts, such as Guanidine hydrochloride , Guanidine nitrate , Guanidine carbonate , Guanidine sulfate .
Guanidine Production
Guanidine (CAS NO.113-00-8) can be pbtained from the role of Calcium and Ammonium iodide or the reaction of Urea and Ammonia under pressurized.

Guanidine Safety Profile
Poison by intraperitoneal and subcutaneous routes. Moderately toxic by ingestion. On heating to 160° it converts to melamine and NH3. Keep well closed. When heated to decomposition it emits toxic fumes of NOx.
Guanidine Specification
Guanidine (CAS NO.113-00-8) is a crystalline compound of strong alkalinity, and also can be called Carbamamidine ; Iminourea ; Guanidinium sulfate ; Bisguanidinium sulfate and Aminoformamidine . There is deliquescence, and it is easy to absorb carbon dioxide from the air tobe strongly alkaline. When heated to 160 °C, it will be decomposed into Melamine and Ammonia .
