Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its stereochemistry allows for high enantioselectivity in drug synthesis, improving efficacy and reducing side effects. Commonly employed in the development of antidepressants and anxiolytic drugs due to its ability to influence neurotransmitter pathways. Also utilized in research settings for asymmetric synthesis and development of novel bioactive molecules.
