It is a derivative of phosphoric acid in which each of the hydroxyl groups have been replaced with an amino group. In bulk, the compound is a white solid which is soluble in polar solvents.
==Chemical properties== Phosphoramide arises from the reaction of phosphoryl chloride with ammonia. In moist air, it hydrolyzes to an ammonium salt: :{{chem2|2 H2O + O\dP(NH2)3 → [NH4]+[PO2(OH)(NH2)]− + NH3}}
It reacts with sodium hydroxide with loss of ammonia:<ref>{{cite journal|journal=Chemische Berichte|title=Phosphoroxy‐triamid und Phosphorthio‐triamid|author=Robert Klement |author2=Otto Koch |volume=87|pages=333–340|year=1954|issue=3|doi=10.1002/cber.19540870308}}</ref> :{{chem2|NaOH + O\dP(NH2)3 → Na+[PO2(NH2)2]− + NH3}}
The related {{ill|thiophosphoryl triamide|qid=Q82903490}} compound {{chem2|S\dP(NH2)3}} was made from the reaction of thiophosphoryl chloride with ammonia.
==Phosphoramides== {{main|Phosphoramides}} Phosphoramide is also the parent compound for a range of derivatives called phosphoramides.<ref>{{GoldBookRef|title=phosphoramides| file = A00484}}</ref> An example compound is the polar solvent hexamethylphosphoramide (HMPA).
