Used primarily in biochemical research to study cellular processes and nucleic acid metabolism. It serves as a nucleoside analog, enabling the investigation of DNA synthesis and repair mechanisms. Often incorporated into DNA to track replication or to induce mutations for genetic studies. Additionally, it has been explored in antiviral research due to its potential to inhibit viral replication. Its azido group allows for further chemical modifications, making it a versatile tool in bioconjugation and labeling experiments.
