Di-p-toluoyl-D-tartaric acid monohydrate is a high-performance chiral resolving agent for enantiomeric separation of pharmaceutical intermediates, particularly basic compounds and sterically hindered amines. Its D-configuration and p-toluoyl groups enhance crystallization selectivity and solubility control, making it ideal for isolating challenging enantiomers. The monohydrate form ensures batch consistency in industrial applications. This compound is widely used in API production, HPLC chiral columns, and asymmetric synthesis. Store in a cool, dry place under inert atmosphere.
