Sodium citrate dihydrate

Description:
Sodium citrate dihydrate is a sodium salt of citric acid, commonly used as a food additive, buffering agent, and anticoagulant in medical applications. Its chemical formula is C6H5Na3O7·2H2O, indicating that it contains two water molecules of hydration. This compound appears as a white, crystalline powder that is highly soluble in water, making it useful in various aqueous applications. Sodium citrate dihydrate has a slightly salty taste and is often employed to enhance flavor and preserve food products. In biochemical contexts, it serves as a buffering agent, helping to maintain pH stability in solutions. Additionally, it plays a role in metabolic processes and can act as a chelating agent, binding metal ions. The substance is generally recognized as safe (GRAS) when used in food, but its use in pharmaceuticals and laboratory settings requires careful consideration of concentration and application. Overall, sodium citrate dihydrate is valued for its versatility and effectiveness in multiple fields, including food science, medicine, and biochemistry.
