Used in pharmaceutical research as a key intermediate in the synthesis of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure supports binding to serotonin receptors, making it valuable in developing antidepressants and anxiolytic drugs. Also explored in the design of enzyme inhibitors due to its sulfonamide linkage and aromatic framework. Limited use in industrial applications; primarily confined to lab-scale synthesis and biological testing.
