Disodium hydrogen citrate sesquihydrate

Description:
Disodium hydrogen citrate sesquihydrate is a chemical compound with the formula C6H6Na2O7·1.5H2O. It is a sodium salt of citric acid, characterized by its crystalline structure and hygroscopic nature, meaning it can absorb moisture from the environment. This compound typically appears as a white to off-white powder and is soluble in water, making it useful in various applications. It serves as a buffering agent, helping to maintain pH levels in solutions, and is often utilized in food and pharmaceutical industries for its stabilizing properties. Additionally, it can act as a mild acidulant and is sometimes employed in formulations to enhance flavor or preserve products. The sesquihydrate form indicates that for every two moles of the anhydrous salt, there are three moles of water, which can influence its stability and solubility. Overall, disodium hydrogen citrate sesquihydrate is valued for its multifunctional roles in both industrial and laboratory settings.
