Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its bromo and ester functional groups allow for further chemical modifications, making it valuable in constructing complex indole-based structures. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to form carbon-carbon bonds. Also utilized in medicinal chemistry research for generating libraries of indole derivatives with potential anti-inflammatory, antiviral, or anticancer activities.
