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 modification, making it valuable in medicinal chemistry for designing drugs with improved binding affinity and selectivity. Commonly employed in research settings to construct complex heterocyclic systems found in bioactive molecules. Also utilized in the preparation of fluorescent probes due to its halogen substitution pattern, which supports further functionalization via cross-coupling reactions.
