What is DAP?

Diammonium phosphate, also known as diammonium hydrogen phosphate (DAP), is a compound fertilizer containing nitrogen and phosphorus.
DAP is a high-efficiency fertilizer widely used in vegetables, fruits, rice, and wheat. 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.
