Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antimicrobial agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to introduce aryl or amine groups, enabling the creation of diverse compound libraries for drug discovery. Also utilized in the preparation of fluorescent probes and materials for organic electronics due to its rigid aromatic framework and favorable electronic properties.
