Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the preparation of heterocyclic compounds such as benzimidazoles and quinoxalines, which exhibit antimicrobial and antitumor activities. It also serves in organic synthesis for introducing brominated aromatic functionalities into complex molecules, enabling further functionalization through cross-coupling reactions. Its reactive aldehyde and ketone groups allow for condensation reactions, making it valuable in the development of dyes, fluorescent probes, and agrochemicals.
