Used primarily in the pharmaceutical industry as a chiral resolving agent to separate enantiomers of racemic mixtures, especially in the production of optically active drugs. Its ability to form diastereomeric salts with racemic amines allows for effective separation through crystallization. Commonly applied in the synthesis of active pharmaceutical ingredients (APIs) where stereochemistry impacts drug efficacy and safety. Also employed in asymmetric synthesis and development of chiral intermediates for antibiotics, antivirals, and cardiovascular medications.
