Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antimicrobial agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for designing bioactive molecules. Also employed in the preparation of fluorescent probes and organic semiconductors due to its electron-deficient aromatic core. Commonly utilized in cross-coupling reactions such as Suzuki and Buchwald-Hartwig to build complex heterocyclic systems for drug discovery and materials science.
