Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the production of selective serotonin reuptake inhibitors (SSRIs). It plays a key role in modifying paroxetine derivatives for improved stability and controlled release in antidepressant formulations. Its structure allows for targeted derivatization, making it valuable in medicinal chemistry for developing analogs with enhanced bioavailability and reduced side effects. Also utilized in research settings for probing metabolic pathways and designing prodrugs.
