Used in pharmaceutical research as a key intermediate in the synthesis of indole-based bioactive compounds. Commonly employed in the development of serotonin receptor modulators and kinase inhibitors due to the indole scaffold’s prevalence in neuroactive and anticancer agents. Its bromo functional group allows for further derivatization via cross-coupling reactions, making it valuable in medicinal chemistry for building complex molecular structures. Also utilized in the preparation of fluorescent probes and imaging agents owing to the inherent optical properties of the indole core.
