Used as a key intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of indole-based drugs. Its structure supports the creation of complex heterocyclic systems found in anti-inflammatory, anticancer, and antimicrobial agents. Commonly employed in organic synthesis for constructing substituted indoles, which are important scaffolds in medicinal chemistry. Also utilized in research settings for designing enzyme inhibitors and receptor ligands due to the reactivity of the bromo and carboxylic acid functional groups.
