Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for targeted cancer therapies. Its structure enables selective binding to enzyme active sites, making it valuable in drug discovery programs focused on oncology and inflammatory diseases. It is also employed in the preparation of fluorescent probes for biochemical assays due to its favorable photophysical properties. Commonly utilized in research laboratories for structure-activity relationship (SAR) studies to optimize potency and selectivity of new drug candidates.
