Product Description:
Sodium hydrogenphosphate dihydrate is widely used as a buffering agent in various biochemical and molecular biology applications. It helps maintain a stable pH in solutions, which is crucial for enzymatic reactions, cell culture media, and protein purification processes. In the food industry, it serves as an emulsifier and stabilizer, particularly in processed cheeses and meat products, to improve texture and shelf life. It is also employed in water treatment to control water hardness and prevent scale formation in boilers and pipes. Additionally, it finds use in pharmaceuticals as an excipient in tablet formulations to regulate acidity and enhance drug stability. In detergents, it acts as a water softener, improving cleaning efficiency by binding to calcium and magnesium ions in hard water.
