Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure enables selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki and Negishi couplings to form carbon-carbon bonds in drug discovery pipelines. Also utilized in the preparation of potent antiviral and anticancer candidates due to its ability to mimic purine scaffolds in nucleoside analogs.
