Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring substituted aromatic aldehydes. Its functional groups—bromo, nitro, and aldehyde—allow for selective reactions such as cross-coupling, reduction, and condensation, making it valuable in constructing complex organic molecules. Commonly employed in the preparation of dyes, fluorescent probes, and heterocyclic compounds due to its reactivity and structural features.
