Used in biochemical research to study RNA and DNA structures due to its ability to mimic natural nucleosides. It plays a role in investigating enzyme mechanisms, particularly those involving nucleoside kinases and transferases. Applied in the development of antiviral and anticancer agents, as it can interfere with nucleic acid synthesis. Also utilized in the synthesis of modified oligonucleotides for therapeutic and diagnostic purposes. Its amino group allows for further chemical modifications, making it valuable in creating probes and labeling molecules for molecular biology studies.
