Cas no 51591-38-9 ((-)-Diacetyl-L-tartaric Acid)

(-)-Diacetyl-L-tartaric Acid is a chiral derivative of L-tartaric acid, characterized by its two acetyl groups. This compound is widely utilized in asymmetric synthesis and resolution processes due to its ability to form diastereomeric salts with racemic mixtures, enabling the separation of enantiomers. Its high optical purity and stability make it a preferred choice for applications in pharmaceuticals, agrochemicals, and fine chemicals. The compound also serves as a versatile intermediate in organic synthesis, particularly in the preparation of chiral catalysts and ligands. Its well-defined stereochemistry and consistent performance underscore its reliability in demanding chemical processes.
