This compound is primarily used in the synthesis of oligonucleotides, particularly in the field of nucleic acid research and therapeutic development. Its modified structure allows for the incorporation of fluorine and arabinose moieties, which can enhance the stability and binding affinity of the resulting oligonucleotides. This makes it valuable in the design of antisense oligonucleotides, siRNA, and other gene-silencing technologies. Additionally, it is employed in the development of diagnostic probes and tools for studying gene function and regulation. Its use in medicinal chemistry is also notable, as it contributes to the creation of novel therapeutics targeting genetic disorders and viral infections.
