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 construction of heterocyclic frameworks found in bioactive molecules. Commonly employed in medicinal chemistry for derivatization to enhance pharmacokinetic properties. Also utilized in research settings for the preparation of benzothiophene-based compounds with potential anticonvulsant, anti-inflammatory, or anticancer activities.
