Trisodium citrate(CAS: 68-04-2)

Trisodium citrate is a sodium salt of citric acid, commonly used as a buffering agent and chelating agent. Its chemical formula is C6H5Na3O7. It is a white crystalline powder that is soluble in water and has a slightly acidic pH. Trisodium citrate is known for its ability to stabilize pH levels and bind metal ions, making it valuable in various industrial and pharmaceutical applications.

Trisodium citrate is widely used in pharmaceuticals as a preservative and stabilizer, in food industry as a flavor enhancer and pH regulator, and in cosmetics for its emulsifying properties. It also serves as a chelating agent in industrial processes to prevent metal ion interference. Additionally, it is used in research for buffer solutions and in medical settings for anticoagulant purposes.

Trisodium citrate is generally considered safe when used in accordance with recommended guidelines. It has low toxicity and is approved for use in food and pharmaceuticals. However, precautions should be taken during handling, especially in high concentrations, to avoid skin or eye irritation. Protective gloves and goggles are recommended for safe usage.

Trisodium citrate should be stored in a cool, dry place away from direct sunlight. It is stable under normal storage conditions but should be kept in a sealed container to prevent moisture absorption. Proper storage helps maintain its chemical integrity and effectiveness, ensuring it remains suitable for its intended applications.
