Used primarily as a key intermediate in the synthesis of pharmaceuticals, especially in the development of serotonin receptor modulators and other neuroactive compounds. Its structure allows for selective modifications, making it valuable in creating analogs for drug discovery related to central nervous system disorders. It is also employed in research settings to develop novel indole-based bioactive molecules with potential antitumor, anti-inflammatory, or antimicrobial properties. The bromine substituent enables cross-coupling reactions, facilitating the construction of complex molecular architectures in medicinal chemistry.
