Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its structure supports functionalization at multiple sites, making it valuable in the development of indole-based drugs. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to form carbon-carbon bonds for constructing complex molecules. Found in research related to serotonin receptor ligands and other neuroactive agents. Also utilized in the synthesis of natural product analogs and in medicinal chemistry for drug discovery.
