Cas no 144-33-2 (Disodium Citrate)

Disodium Citrate, also known as sodium citrate dibasic, is a sodium salt of citric acid with the chemical formula Na?C?H?O?. It is a white, crystalline powder highly soluble in water, exhibiting excellent buffering and chelating properties. As a food additive (E331), it serves as an emulsifier, pH regulator, and preservative, enhancing stability and shelf life in dairy products, beverages, and processed foods. In pharmaceuticals, it acts as an anticoagulant in blood collection tubes and a urinary alkalizer. Its biocompatibility and non-toxicity make it suitable for medical and cosmetic applications. Disodium Citrate is also valued in industrial processes for its ability to sequester metal ions, improving detergent efficiency and water treatment. Its versatility and safety profile underscore its utility across multiple sectors.
