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)

Reactions with nucleosides
DAP phosphorylates deoxynucleosides (the building blocks of DNA, and at the same time initiates polymerization to make DNA. DAP facilitates the synthesis of larger RNA sequences (ribozymes) from smaller RNA strands. Other nitrogenous derivatives of phosphorus derivatives have also been proposed in this context in a review article.
