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 settings for the preparation of potential antipsychotic and antidepressant drugs. Also utilized in medicinal chemistry for building blocks in the design of novel bioactive molecules due to its rigid, fused ring system and fluorinated substitution pattern, which can enhance metabolic stability and binding affinity.
