Product Description

 

Product Description

application:
Diamidophosphate (DAP)   is the simplest   phosphorodiamidate   ion, with formula PO 2 (NH 2 ) 2 − . It is a   phosphorylating   ion and was first used for phosphorylation of sugars in aqueous medium.   DAP has attracted interest in the area of primordial chemistry.

Heating anhydrous sodium diamidophosphate causes polmerization:

· At 160 °C, Na 2 P 2 O 4 (NH)(NH 2 ) 2 , Na 3 P 3 O 6 (NH) 2 (NH 2 ) 2 , Na 4 P 4 O 8 (NH) 3 (NH 2 ) 2 , Na 5 P 5 O 10 (NH) 4 (NH 2 ) 2  and Na 6 P 6 O 1 2 (NH) 5 (NH 2 ) 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) 3 P(NH 2 )NHAg, and pentasilver orthodiamidophosphate (AgO) 3 P(NHAg) 2 .

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.
