Disodium Hydrogen Phosphate Dihydrate (Na₂HPO₄·2H₂O)

Disodium Hydrogen Phosphate Dihydrate is the hydrated form of disodium hydrogen phosphate, a white crystalline powder commonly used as a buffering agent, emulsifier, and sequestrant. The dihydrate form contains two water molecules per formula unit, which affects its physical properties such as melting point and solubility. It is widely applied in food, pharmaceutical, water treatment, and industrial processes to maintain pH stability, improve texture, and supply essential sodium and phosphate ions.
