2-Hydrazinoadenosine is primarily used in biochemical research as a tool to study enzyme mechanisms and nucleic acid interactions. It serves as a modified nucleoside that can be incorporated into RNA or DNA to investigate the structure and function of these molecules. Additionally, it is utilized in the synthesis of adenosine analogs, which are valuable for probing the active sites of enzymes like adenosine deaminase. Its hydrazine group allows for specific chemical modifications, making it a versatile reagent in the development of nucleotide-based probes and inhibitors. This compound is also employed in studies related to purine metabolism and the design of potential therapeutic agents targeting nucleic acid-related processes.
