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 medicinal chemistry for creating analogs with enhanced biological activity. Commonly employed in cross-coupling reactions to introduce aryl or heteroaryl groups, facilitating the construction of complex molecules in drug discovery programs. Also utilized in the preparation of fluorescent probes for biochemical assays due to its favorable photophysical properties.
