Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of central nervous system agents and antidepressants. Its enantiomeric purity makes it valuable in asymmetric synthesis, where it helps control stereochemistry in complex molecules. Also employed in the development of agrochemicals and fine chemicals requiring specific optical activity. Commonly used in research settings for the preparation of amides, sulfonamides, and other nitrogen-containing compounds with defined stereochemistry.
