Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antiviral and anticancer agents. Its structure allows for selective binding to biological targets, making it valuable in medicinal chemistry for designing inhibitors and receptor modulators. Commonly employed in research settings to build more complex heterocyclic systems with enhanced bioactivity. Also utilized in the preparation of kinase inhibitors and in the discovery of new central nervous system (CNS) active drugs due to its ability to cross the blood-brain barrier.
