Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nitrogen-containing heterocyclic compounds. Its functional groups—bromine, aldehyde, and nitro—allow for selective reactions such as cross-coupling, reduction, and condensation, making it valuable in constructing complex drug molecules. Commonly employed in the preparation of kinase inhibitors and antimicrobial agents. Also utilized in agrochemical research for designing bioactive molecules with enhanced stability and reactivity.
