Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active compounds. Its enantiomeric purity is critical for achieving desired biological activity and minimizing side effects in final drug formulations. Commonly employed in asymmetric synthesis routes where the (S)-configuration enhances binding affinity to neurotransmitter receptors. Also utilized in the development of agrochemicals and bioactive molecules requiring high stereochemical precision.
