Used primarily in medical and biological research, this compound serves as a thymidine analog, incorporating into DNA to study cell proliferation and DNA synthesis. It is particularly valuable in tracking the division of cells in cultures or tissues, making it a useful tool in cancer research to monitor tumor growth and the effectiveness of anticancer treatments. Additionally, it is employed in virology to investigate the replication mechanisms of viruses, providing insights into viral behavior and potential therapeutic targets. Its ability to be detected through specific antibodies or fluorescence techniques enhances its utility in visualizing and quantifying cellular processes.
