Ammonium phosphate monobasic is employed as a flameproofing agent, a fertilizer, food additive and in fermentations (yeast preparations). Prevents afterglow in matches. Also used in the synthesis of the first example of a mixed-valence ammonium iron phosphate, NH4Fe2(PO4)2.A water soluble preparation of ammonium phosphate.
