Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Particularly valuable in the development of indole-based drug candidates due to its reactive bromo and ester functional groups. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to construct complex indole derivatives. Also utilized in the synthesis of natural product analogs and in medicinal chemistry for exploring new therapeutic agents targeting inflammation, cancer, and neurological disorders. Its structure allows for easy modification, making it a versatile building block in heterocyclic chemistry.
