Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antiviral and anticancer agents. Its structure allows for modification at multiple sites, making it valuable in medicinal chemistry for designing purine-based analogs. It has been investigated in the preparation of kinase inhibitors and nucleoside derivatives that interfere with DNA replication in rapidly dividing cells. Additionally, it serves as a building block in the creation of biologically active molecules targeting viral polymerases and cellular signaling pathways.
