Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the formation of biologically active molecules that target specific signaling pathways in tumor cells. Commonly employed in medicinal chemistry for optimizing drug candidates due to its favorable reactivity and ability to mimic purine-like scaffolds in nucleotide-binding sites. Also utilized in research settings to design new analogs with improved potency and selectivity.
