This compound is primarily used in antiviral research, particularly in the study of herpes simplex virus (HSV) infections. It functions as a thymidine analog, which is incorporated into viral DNA during replication, leading to the inhibition of viral DNA synthesis. This mechanism makes it effective in reducing the replication of HSV in laboratory settings. Additionally, it has been explored for its potential in diagnostic applications, such as in the development of assays to detect viral activity. Its role in research extends to understanding the molecular mechanisms of antiviral agents and their interactions with viral enzymes.
