Used primarily as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals targeting kinase enzymes. It serves as a building block in the preparation of purine-based analogs that exhibit antiviral, anticancer, and anti-inflammatory properties. Its structure allows for selective modifications, making it valuable in medicinal chemistry for designing inhibitors that interfere with cellular signaling pathways. Commonly employed in research settings to develop potential drug candidates, especially in oncology and antiviral therapy.
