The invention discloses a method for synthesizing an ammonium dihydrogen phosphate compound. The method comprises the following steps: dissolving ammonium dihydrogen phosphate in deionized water, preparing a super-saturated solution at a certain temperature, dissolving organic sugar in deionized water, preparing an organic sugar solution with a certain mass percent at the temperature, uniformly mixing the two solutions in a stirring state, and standing for later use; and adding the mixed solution into an organic solvent in a stirring state according to a certain speed, standing at room temperature after the addition is finished, filtering to obtain a crystallized product, drying the obtained crystallized product at low temperature, and preparing to obtain the ammonium dihydrogen phosphate compound. According to the invention, ammonium dihydrogen phosphate and organic sugar can be mixed on the molecular scale, and the method has the characteristic that the phase distribution is uniform, so that a phenomenon that the carbon cladding is non-uniform due to non-uniform mixing of a carbon source in the process of synthesizing lithium iron phosphate in an organic solvent system by taking ammonium dihydrogen phosphate as a raw material.
