Sodium Phosphate Dibasic Monohydrate is a common inorganic compound with a wide range of applications in food, industry, and pharmaceuticals. Here are its main uses:
1. Food Industry
pH Regulator: It is used to adjust the acidity or alkalinity of food, helping to maintain stability and texture.
Emulsifier: In food processing, it acts as an emulsifier to prevent separation of oil and water, commonly used in products like salad dressings and mayonnaise.
Preservative: By adjusting the pH value, it inhibits the growth of microorganisms, thereby extending the shelf life of food.
Nutritional Supplement: Phosphates are essential minerals for the human body, and Sodium Phosphate Dibasic Monohydrate can be used as a source of phosphorus in fortified foods.
Dough Improver: In baking, it can improve the structure and texture of dough, enhancing the elasticity and toughness of bread.
2. Pharmaceutical Field
Pharmaceutical Excipient: It serves as a buffer, stabilizer, or pH regulator in drug formulations, used in the preparation of tablets, capsules, and injections.
Medical Use: In certain medical procedures, it can be used to regulate the acid-base balance of body fluids, for example, as an auxiliary component in the treatment of metabolic acidosis.
3. Industrial Applications
Water Treatment: It is used to soften water by removing calcium and magnesium ions, preventing the formation of scale.
Cleaning Agents: As a component in cleaning products, it helps remove grease and stains, commonly found in industrial and household cleaning solutions.
Electroplating Industry: In electroplating processes, it acts as an electrolyte to help form a uniform coating.
Ceramics and Glass Industry: It serves as a flux, lowering the melting point of ceramics and glass to improve their performance.
4. Laboratory Uses
Buffer Solution: It is used to prepare phosphate-buffered saline (PBS), which is widely used in biochemical experiments and cell culture.
Analytical Reagent: It is used as a reagent in analytical chemistry for titration and precipitation reactions.
