Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves in the development of kinase inhibitors and other targeted therapies due to its ability to participate in cross-coupling reactions, enabling the formation of complex heterocyclic systems. Its halogen substituents allow selective functionalization, making it valuable in drug discovery for optimizing potency and selectivity. Also employed in the preparation of fluorescent probes and labeled compounds for biochemical assays.
