Used primarily as an intermediate in the synthesis of antiviral medications, particularly in the development of nucleoside analogs. It plays a key role in modifying purine structures to enhance biological activity against viruses such as herpes simplex and varicella-zoster. Its methoxymethyl group at the 9-position improves cell permeability and metabolic stability, making it valuable in prodrug design. Also explored in research for potential anticancer agents due to its ability to interfere with viral and cellular DNA replication.
