Used primarily in biochemical research, this compound serves as a nucleoside analog in the study of DNA synthesis and repair mechanisms. It is particularly valuable in radio-labeling experiments due to the presence of iodine, which allows for easy tracking and detection. Additionally, it plays a role in antiviral research, where it is investigated for its potential to inhibit viral replication by incorporating into viral DNA, thereby disrupting its function. In cancer research, it is explored for its ability to interfere with the DNA of rapidly dividing cells, offering a pathway for developing targeted therapies. Its applications extend to molecular biology, where it aids in understanding the structural and functional aspects of nucleic acids.
