8-Bromoadenosine is widely used in biochemical research as a modified nucleoside to study RNA and DNA interactions. It serves as a valuable tool in probing the structure and function of nucleic acids due to its ability to mimic adenosine while introducing steric and electronic changes. This compound is particularly useful in investigating enzyme mechanisms, such as those involving adenosine deaminase and kinases, as it can act as a substrate or inhibitor. Additionally, 8-Bromoadenosine is employed in the synthesis of fluorescent or labeled nucleosides for tracking and imaging applications in cellular studies. Its incorporation into oligonucleotides helps in understanding the role of specific nucleotides in biological processes, making it a key reagent in molecular biology and drug development research.
