It is also used in animal feed, food, printing and plate making, medicine, fire prevention, electronic tubes and other industries. Application:Diamidophosphate (DAP) is the simplest phosphorodiamidate ion, with formula PO2(NH2)2?. It is a phosphorylating ion and was first used for the phosphorylation of sugars in an aqueous medium. DAP has attracted interest in the area of primordial chemistry.Heating anhydrous sodium diamidophosphate causes polmerization:·At 160 °C, Na2P2O4(NH)(NH2)2, Na3P3O6(NH)2(NH2)2, Na4P4O8(NH)3(NH2)2, Na5P5O10(NH)4(NH2)2 and Na6P6O12(NH)5(NH2)2 are produced. These substances contain P-N-P backbones. These can be separated by paper chromatography.·At 200 °C the hexa-phosphate is produced.·At 250 °C the typical chain length is 18.Diamidophosphate inhibits urease enzymes by blocking up the active site, binding to two nickel centers. Diamidophosphate mimics the urea hydrolysis intermediate.Diamidophosphate is tribasic, and the amine groups may also lose hydrogen to form more metallic salts. With silver, further reactions can yield explosive salts: tetrasilver orthodiamidophosphate (AgO)3P(NH2)NHAg, and pentasilver orthodiamidophosphate (AgO)3P(NHAg)2.
