Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of selective kinase inhibitors and other biologically active compounds. It serves as a building block in organic reactions, especially in cross-coupling and condensation reactions, due to the presence of both aldehyde and nitro groups. Its bromo substituent allows for further functionalization via metal-catalyzed coupling reactions like Suzuki or Heck reactions. Commonly employed in research laboratories for the development of fluorescent probes and sensors owing to its ability to form Schiff bases. Also utilized in the preparation of dyes and photoactive materials.
