At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the fundamental importance of understanding the precise chemical properties of the materials we supply. Diammonium Hydrogen Phosphate, identified by CAS number 7783-28-0, is a compound whose chemical characteristics are central to its wide-ranging industrial utility.

The molecular formula for Diammonium Hydrogen Phosphate is (NH4)2HPO4, with a molar mass of approximately 132.06 g/mol. This inorganic salt typically presents as a colorless to white crystalline solid. Its solubility in water is a key attribute, with significant dissolution rates at various temperatures, making it amenable to aqueous applications. For instance, it is highly soluble in water, with solubility increasing with temperature. A 1% solution typically exhibits a pH in the range of 7.6 to 8.2, classifying it as a slightly alkaline substance in solution. This pH characteristic is important in many of its applications, including its use as a buffer or pH regulator.

The manufacturing of diammonium phosphate involves the reaction of ammonia with phosphoric acid. The precise control of this reaction is critical to achieving the desired purity, often specified as 99% or higher for specialized applications. The process typically involves careful stoichiometric control to ensure the formation of the diammonium salt. Understanding the manufacturing processes and quality control measures is vital for businesses seeking to buy diammonium hydrogen phosphate that consistently meets their specifications.

The industrial significance of diammonium hydrogen phosphate cannot be overstated. In agriculture, it is a premier fertilizer, providing essential nitrogen and phosphorus. Its high phosphorus content is particularly beneficial for root development and flowering. Beyond agriculture, its role as a fire retardant is well-documented. When heated, DAP decomposes, releasing gases that interfere with the combustion process. This makes it an effective additive in fire-fighting chemicals and materials intended to resist ignition.

Furthermore, diammonium hydrogen phosphate serves as a vital intermediate in the synthesis of other chemical products and is used as a food additive for its leavening and pH-adjusting properties. The market for diammonium phosphate is robust, driven by demand from these diverse sectors. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to ensuring a reliable supply of high-quality diammonium phosphate, supporting the manufacturing and innovation efforts of our clients.

For businesses looking to source this essential chemical, exploring options for purchasing diammonium hydrogen phosphate and understanding its technical specifications, such as purity levels and physical form, are crucial steps. The consistent quality and chemical integrity of diammonium phosphate are paramount for its successful application in agriculture, industry, and beyond.
