Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. Its structure supports the creation of selective receptor modulators, including those targeting dopamine and serotonin receptors. Commonly employed in research for antipsychotic and antidepressant drug candidates. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of halogen substituents that influence binding affinity and metabolic stability.
