Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for cancer therapeutics. Its structure enables selective binding to enzyme active sites, making it valuable in developing targeted therapies. Also employed in the preparation of fluorescent probes for biochemical assays due to its favorable photophysical properties. Commonly utilized in cross-coupling reactions, such as Suzuki and Buchwald-Hartwig, to build complex heterocyclic systems in drug discovery.
