Used in pharmaceutical research as a key intermediate in the synthesis of selective serotonin reuptake inhibitors (SSRIs) and related central nervous system agents. Its structural framework supports the development of compounds with potential antidepressant and anxiolytic activities. The (Z)-configuration is critical for biological activity, enabling optimal interaction with neurotransmitter receptors. Also explored in the design of novel benzodiazepine analogs with improved selectivity and reduced side effect profiles.
