Phosphamidic acid

Phosphorylation is the process of introducing enzymatically a phosphoric acid residue into a protein from ATP as a phosphoryldonor. This results in the formation of a covalent phosphoric acid ester with the OH-groups of serine/threonine or with the phenolic group of tyrosine residues, or the formation of a phosphamide in N-phosphohistidine. 

Most of the phosphoric series possess at least one PN bond, viz., the esters (83 R = Ar, COPh), the chloroamide (84), some phosphamides, a diazadiphosphetidine, several cyclophosphazenes, and three thioamides, e.g., (85). Other studies were directed towards adenosine monophosphate, salts of phosphoenolpyruvate, 0-ethyl-0-phenyl phosphorothioic acid, and a phosphobiotin model. ...

Palladium chloride detects phosmethylan (55) with 0.5 pg/spot sensitivity. This reaction was used for quinalphos (7), phosphamide (8), and methamidophos in food samples (154) as well. Malathion residues were studied in pharmaceutical preparations by dipping plates into a 0.1 % solution of palladium chloride in hydrochloric acid, yielding yellow spots that could be quantitatively determined by scanning at 400 nm (159).
