Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active compounds. Its structure supports the formation of bioactive molecules with improved metabolic stability and receptor binding affinity. Commonly employed in medicinal chemistry for constructing heterocyclic scaffolds in drug discovery programs targeting neurological disorders. Also utilized in the preparation of functionalized benzothiophene derivatives for research in organic electronics due to its electron-rich nature and thermal stability.
