 Ammonium ethyl carbamoyl-phosphonate ,its CAS number is 25954-13-6,it can be called Ammonium ethyl (aminocarbonyl)phosphonate ; phosphonic acid, P-(aminocarbonyl)-, ethyl ester, ammonium salt .

 Ammonium ethyl carbamoyl-phosphonate (CAS NO. 25954-13-6) is a white crystalline solid, slightly scented with mint. For organic phosphorus it can be used as plant growth regulators, and its production method is to slowly dropwise added methyl chloroformate three sub-phosphonic acid ethyl ester, in the heat under the conditions of rearrangement reaction of methoxycarbonyl phosphonate ethyl ester. Then, in toluene solution through ammonia generation amino formyl Diethyl. Finally reaction with ammonia, concentrated by the separation, the system can get adjust phosphine.

 It is a low toxic substance,with flammability, burning will produce It is a moderate toxic substance,with flammability, burning will produce toxic fluoride, nitrogen oxide, vanadium oxide and ammonia fumes,so it should be stored in cool and dry environment,dry powder,foam,sand, carbon dioxide,water mist can be used if something urgent happened,so it should be stored in cool and dry environment,dry powder,foam,sand, carbon dioxide,water mist can be used if something urgent happened.
