Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeted cancer therapies. Its structure enables selective modification to develop compounds with high binding affinity to specific enzyme active sites. Commonly employed in the preparation of indolopyridine-based drug candidates that modulate signaling pathways involved in tumor growth and inflammation. Also utilized in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig, to introduce aryl or amino groups during medicinal chemistry optimization.
