Used primarily as an intermediate in the synthesis of biologically active compounds, particularly in the development of kinase inhibitors for cancer research. Its halogenated structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing purine-based analogs. It has been employed in the preparation of potential antiviral and anticancer agents due to its ability to modulate cellular signaling pathways. The presence of iodine facilitates radiolabeling applications, enabling use in tracer studies and imaging probes.
