Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and anticancer agents. Its bromine functionality allows for further derivatization via cross-coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems. Also employed in coordination chemistry as a ligand for metal ions, aiding in the design of catalysts or luminescent materials. The carboxylic acid group enables salt formation and improves solubility for biological testing.
