Application

Sodium Phosphate Dibasic Dodecahydrate serves multiple purposes in various fields. It appears as white crystals and plays a crucial role in the preparation of self-supporting membranes. This colorless crystalline sodium salt is used extensively as a buffer in molecular biology, biochemistry, and chromatographic studies. It comes in three forms-monobasic, dibasic, and tribasic-but the dibasic form is particularly significant due to its versatility. In pharmaceutical applications, it acts as a buffering and sequestering agent and serves therapeutic purposes as a mild laxative and in treating hypophosphatemia. Moreover, it finds utility in the food industry, such as functioning as an emulsifier in processed cheese products.
