Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its structure supports the development of serotonin receptor modulators and central nervous system agents. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to build complex heterocyclic systems for drug discovery. Also utilized in the preparation of potential antipsychotic and antidepressant candidates due to the carbazole scaffold’s affinity for neurological targets.
