Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure enables functionalization at multiple sites, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build biologically active molecules. Also utilized in the preparation of fluorescent probes and materials for organic electronics due to its electron-rich aromatic framework.
