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 heterocyclic frameworks common in modern drug design. It is also employed in the preparation of benzothiophene-based derivatives for research in anti-inflammatory and anticonvulsant therapies. Additionally, it serves as a building block in agrochemicals for creating novel pesticides with improved efficacy and selectivity.
