    Product Description:
    Disodium hydrogen phosphate dodecahydrate is an inorganic salt with the chemical formula Na₂HPO₄·12H₂O. It appears as colorless or white crystalline granules or powder and is highly soluble in water, forming an alkaline solution. Its primary applications are as a pH buffer, emulsifier, and nutrient source across multiple regulated industries. In pharmaceuticals, it is a critical excipient used as a buffering agent to maintain the pH and stability of injectable solutions, oral medications, and topical formulations. In the food industry, it functions as an acidity regulator, emulsifying salt in processed cheeses, and a nutrient supplement. It also finds use in water treatment as a corrosion inhibitor and in molecular biology as a component of buffer solutions for biochemical assays. As a general laboratory reagent, it serves as a source of phosphate ions. Handling requires standard precautions for laboratory chemicals, and it should be stored in a cool, dry place to prevent efflorescence or caking.
