Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. It serves as an intermediate in the preparation of central nervous system agents, including certain antidepressants and anti-Parkinson drugs. Its enantiomeric purity makes it valuable in asymmetric synthesis and resolution processes. Also employed in the development of agrochemicals and fine chemicals requiring specific optical activity.
