CAS 32634-66-5: (-)-Di-p-toluoyl-L-tartaric acid

Description: (-)-Di-p-toluoyl-L-tartaric acid is a chiral organic compound that belongs to the class of tartaric acid derivatives. It is characterized by the presence of two p-toluoyl groups attached to the tartaric acid backbone, which contributes to its unique stereochemical properties. This compound is typically used as a resolving agent in asymmetric synthesis, particularly in the resolution of racemic mixtures of amines and alcohols, due to its ability to form diastereomeric salts with enantiomers. The presence of the bulky p-toluoyl groups enhances its selectivity in chiral recognition processes. (-)-Di-p-toluoyl-L-tartaric acid is generally a white to off-white crystalline solid, and it is soluble in organic solvents such as ethanol and acetone, but less soluble in water. Its applications extend to the pharmaceutical industry, where it plays a role in the development of chiral drugs. As with many tartaric acid derivatives, it exhibits optical activity, making it useful in studies involving chirality and stereochemistry.
