Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective functionalization, making it valuable in constructing biologically active molecules. Commonly employed in medicinal chemistry for creating analogs in drug discovery programs targeting neurological disorders and oncology. Also utilized in the preparation of fluorescent probes due to its heterocyclic framework, which can enhance binding affinity and selectivity in molecular imaging.
