Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system agents. Commonly employed in the preparation of indole-based bioactive compounds due to its reactive bromo and nitrile functional groups, which allow for further chemical modifications through cross-coupling reactions and nucleophilic substitutions. Also utilized in research settings for the design of novel anticancer, anti-inflammatory, and antimicrobial agents. Its structural features make it valuable in medicinal chemistry for building complex heterocyclic systems.
