Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for further functionalization, making it valuable in medicinal chemistry for constructing heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build complex molecules for drug discovery. Also utilized in agrochemical research for designing new active ingredients in crop protection agents. Its bromo and aldehyde functional groups provide versatile reaction sites for multi-step organic synthesis.
