Used primarily in biochemical research, this compound serves as a nucleoside analog. It plays a crucial role in studying DNA synthesis and repair mechanisms. Researchers utilize it to investigate the incorporation of modified nucleotides into DNA, which helps in understanding cellular processes and the effects of genetic mutations. Additionally, it is employed in the development of antiviral and anticancer therapies, where it acts to inhibit the replication of certain viruses and cancer cells by disrupting their DNA synthesis. Its application extends to molecular biology techniques, including polymerase chain reaction (PCR), where it aids in the study of DNA replication fidelity and enzyme kinetics.
