Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active agents. Its fluorinated benzothiophene core enhances metabolic stability and binding affinity to target receptors. Commonly employed in medicinal chemistry for constructing bioactive molecules due to its favorable electronic and steric properties. Also utilized in the preparation of novel heterocyclic compounds for drug discovery research.
