Potassium dihydrogen phosphate is a chemical with the chemical formula KH2PO4. Deliquescent. When heated to 400 ° C, it melts into a transparent liquid, and after cooling, it solidifies into an opaque glassy potassium metaphosphate. Stable in air, soluble in water, insoluble in ethanol. It is also used as a flavoring agent for synthesizing sake in a bacterial culture, a raw material for producing potassium metaphosphate, a culture agent for forging yeast, a fortifier, a leavening agent, and a fermentation aid. It is used as a high-efficiency phosphorus and potassium compound fertilizer in agriculture.

Application
It is used as high-efficiency phosphorus-potassium compound fertilizer in agriculture; potassium dihydrogen phosphate product is widely used in almost all types of crops such as various types of economic crops, grain, fruits, vegetables, etc. Potassium dihydrogen phosphate has significant increase in yield and income, and optimization of quality. It has many excellent effects, such as lodging resistance, resistance to diseases and insect pests, prevention and treatment of premature aging, and has the effect of overcoming the nutritional deficiencies caused by the decline of root aging absorption ability in the late stage of crop growth. Potassium dihydrogen phosphate is a new high-concentration phosphorus-potassium two-element compound fertilizer, which contains about 52% of phosphorus pentoxide and about 34% of dipotassium oxide. Potassium dihydrogen phosphate is an ideal new fertilizer for flue-cured tobacco. Potassium dihydrogen phosphate can be used on cotton to control the length of cotton and increase the number of flower buds. Potassium dihydrogen phosphate is widely used in drip irrigation systems.
