Calcium dihydrogen phosphate (Ca(H2PO4)2) is widely used in the following fields:
1.Feed additive: Calcium dihydrogen phosphate is one of the commonly used feed phosphorus sources, which can provide phosphorus elements for poultry, livestock and other animals, and promote growth and bone formation.
2.Food processing: Calcium dihydrogen phosphate can be used as acidity regulator, leavening agent and pH regulator in food processing. It can improve the texture, taste and freshness of foods.
3.Water treatment agent: Calcium dihydrogen phosphate can be used as rust remover, corrosion inhibitor and scale control agent in water treatment process. It can combine with metal ions to form insoluble salts, reduce the content of metal ions in water, and protect pipelines and equipment.

4.Pharmaceutical field: Calcium dihydrogen phosphate can be used as an acidity regulator and buffer in pharmaceutical preparations to help stabilize and improve solubility of drugs at an appropriate pH value.
5.Agricultural field: Calcium dihydrogen phosphate can be used as an auxiliary agent in the formulation and preparation of pesticides to improve their stability and solubility.

NOTE: It should be noted that calcium dihydrogen phosphate is a strong acidic substance, and relevant safety operating procedures should be followed when using it, and personal protective measures should be paid attention to.
