Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its halogenated structure allows for selective cross-coupling reactions, enabling the construction of complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry research for structure-activity relationship (SAR) studies due to its ability to modulate electronic and steric properties in drug candidates. Also utilized in the preparation of fluorescent probes and labeled compounds for biochemical assays.
