Used primarily in biochemical research, this compound serves as a modified nucleoside to study nucleic acid metabolism and enzyme mechanisms. It is particularly valuable in investigating the role of thymidine analogs in DNA synthesis and repair processes. Additionally, it finds application in the development of antiviral and anticancer agents, where its incorporation into nucleic acids can inhibit the replication of viral or tumor DNA. Researchers also utilize it to explore the effects of nucleoside modifications on gene expression and cellular function.
