Used primarily in the field of molecular biology and biochemistry as a nucleoside analog, it plays a crucial role in the study of DNA synthesis and repair mechanisms. It is often incorporated into DNA sequences to inhibit the replication of certain viruses, making it valuable in antiviral research. Additionally, it serves as a precursor in the synthesis of more complex nucleoside derivatives, which are explored for their potential therapeutic applications, particularly in cancer and viral infection treatments. Its ability to interfere with nucleic acid metabolism also makes it a useful tool in genetic and biochemical studies aimed at understanding cellular processes and developing targeted therapies.
