Diammonium phosphate （DAP， CAS 7783-28-0）
Product name: Diammonium phosphate
Chemical Formula: (NH4)2HPO4
CAS Number: 7783-28-0
PN12049 Diammonium phosphate is used as a fertilizer. When applied as plant food, it temporarily increases the soil pH, but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium. DAP can be used as a fire retardant. It lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char.
