Used as a chiral resolving agent in organic synthesis, particularly for the separation of enantiomers of basic compounds through diastereomeric salt formation. It is commonly employed in the resolution of amines and amino derivatives due to its acidic nature and well-defined stereochemistry. The compound facilitates purification in the production of optically active pharmaceuticals and fine chemicals. Its utility in classical resolution methods makes it valuable in asymmetric synthesis and development of chiral intermediates.
