Used as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the development of selective COX-2 inhibitors. Its structure allows for effective binding and modulation of inflammatory pathways. Commonly employed in pharmaceutical research to build biologically active molecules due to the stability and reactivity of the benzothiophene core. Also utilized in the preparation of analogs for structure-activity relationship (SAR) studies targeting anti-inflammatory and analgesic agents.
