Used in organic synthesis as an intermediate for pharmaceuticals and biologically active compounds. Serves as a building block in the preparation of indole-based derivatives, which are common structures in medicinal chemistry. Particularly valuable in the development of kinase inhibitors and anticancer agents due to the indole scaffold’s affinity for various enzyme targets. Also employed in research settings to study structure-activity relationships in heterocyclic compounds. Its bromo substituent allows for further functionalization via cross-coupling reactions, enhancing its utility in drug discovery and materials science.
