Used in biochemical research to study nucleoside metabolism and DNA synthesis pathways. It serves as a precursor in the synthesis of modified nucleosides and nucleotides, which are valuable in antiviral and anticancer drug development. In molecular biology, it is employed as a tool to investigate the mechanisms of DNA repair and replication. Additionally, it is utilized in the production of labeled compounds for diagnostic imaging and as a substrate for enzymatic studies to understand cellular processes. Its role in modulating nucleotide pools also makes it relevant in studies related to cellular stress and apoptosis.
