Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and anticancer agents. Its structure allows for selective binding to enzyme targets, making it valuable in drug discovery. Commonly employed in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig, to build complex heterocyclic systems found in bioactive molecules. Also utilized in research settings for the design of fluorescent probes and imaging agents due to its favorable photophysical properties when modified.
