Calcium hydrogen phosphate dihydrate, also known as dicalcium phosphate dihydrate, is a chemical compound with the formula CaHPO4·2H2O. It is composed of calcium ions (Ca2+), hydrogen phosphate ions (HPO42-), and water molecules (H2O). This compound is a white, odorless, and crystalline powder with a molecular weight of approximately 172.09 g/mol.

Calcium hydrogen phosphate dihydrate has various applications in industries such as pharmaceuticals, food, and agriculture due to its unique properties and nutritional benefits. It plays a crucial role in supporting human health, enhancing food products, and promoting plant growth.

In the pharmaceutical industry, calcium hydrogen phosphate dihydrate is commonly used as a calcium and phosphorus supplement. It is often formulated into tablets and capsules to provide essential nutrients for maintaining healthy bones and teeth. Calcium and phosphorus are vital for various physiological processes, including bone mineralization, nerve function, and muscle contraction. By incorporating calcium hydrogen phosphate dihydrate into pharmaceutical products, it helps to meet the dietary requirements of these essential minerals.

In the food industry, calcium hydrogen phosphate dihydrate serves as a nutrient fortifier and an anti-caking agent. It is added to a wide range of food products, such as cereals, dairy items, and beverages, to enhance their nutritional content. Calcium is essential for bone health and proper nerve function, while phosphorus plays a crucial role in energy metabolism and cellular processes. By fortifying foods with calcium hydrogen phosphate dihydrate, manufacturers can contribute to the nutritional needs of consumers.

Furthermore, calcium hydrogen phosphate dihydrate acts as an anti-caking agent in powdered food products. It helps to prevent the formation of lumps and improve the flowability of powders, ensuring consistent product quality and ease of handling. This property makes it particularly useful in powdered mixes, spices, and condiments, where maintaining a free-flowing texture is essential.

In the agricultural sector, calcium hydrogen phosphate dihydrate is used as a fertilizer component. It provides plants with a readily available source of calcium and phosphorus, two essential nutrients for plant growth and development. Calcium is involved in cell wall formation, enzyme activation, and nutrient uptake in plants. Phosphorus is critical for energy transfer, DNA synthesis, and root development. By incorporating calcium hydrogen phosphate dihydrate into fertilizers, farmers can enhance soil fertility and promote healthier crops.

In summary, calcium hydrogen phosphate dihydrate is a versatile compound with diverse applications in pharmaceuticals, food, and agriculture. It offers nutritional benefits by providing essential minerals like calcium and phosphorus. Its use as a nutrient fortifier and anti-caking agent in food products improves their quality and enhances consumer health. Additionally, as a fertilizer component, it supports plant growth and contributes to agricultural productivity.
