Disodium tartrate (Na2C4H4O6), commonly known as a high-purity salt of tartaric acid, is an industrial-grade compound used primarily in food processing and pharmaceuticals. It appears as a white crystalline powder and is often employed as a buffering agent, emulsifier, and stabilizer. Disodium tartrate is typically synthesized through neutralization of tartaric acid with sodium carbonate. Stored at room temperature in moisture-resistant containers, it ensures long shelf life and stability. Industries such as food, cosmetics, and chemical manufacturing rely on disodium tartrate for its functional properties. Its safety profile allows for a variety of applications, although proper handling practices are recommended.
