Used as a substrate in enzymatic assays to study the activity of enzymes like nucleoside phosphorylase and adenosine deaminase. It plays a role in nucleotide metabolism research, helping to understand pathways related to DNA synthesis and repair. In molecular biology, it is utilized in polymerase chain reaction (PCR) to study mutations or nucleotide incorporation. Additionally, it is employed in the development of antiviral and anticancer drugs, as it can mimic natural nucleotides and interfere with viral or cancer cell replication. Its sodium salt form enhances solubility, making it suitable for various biochemical and pharmaceutical applications.
