Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antimicrobial agents. Its structure enables functionalization at multiple sites, making it valuable in medicinal chemistry for constructing biologically active molecules. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to generate diverse compound libraries for drug discovery. Also utilized in the preparation of fluorescent probes and optoelectronic materials due to its aromatic and heterocyclic nature.
