Used in the synthesis of biologically active compounds, particularly in the development of kinase inhibitors for cancer therapy. Serves as a key intermediate in pharmaceutical research due to its structural similarity to purine bases, enabling incorporation into nucleoside analogs with potential antiviral or anticancer activity. Also employed in the design of selective enzyme inhibitors targeting inflammatory and neurodegenerative diseases. Its scaffold is valued in medicinal chemistry for enhancing binding affinity and metabolic stability in drug candidates.
