Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nitrogen-containing heterocyclic compounds with potential biological activity. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to construct complex aromatic systems for drug discovery. Also utilized in the preparation of fluorescent dyes and optoelectronic materials due to its rigid aromatic structure and ability to participate in π-conjugated systems. Its bromine functionality allows for selective functionalization, making it valuable in combinatorial chemistry and the design of kinase inhibitors and antimicrobial agents.
