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 atoms into the DNA or RNA sequence, enhancing the stability and binding affinity of the resulting oligonucleotides. This makes it valuable in applications such as antisense therapy, where modified oligonucleotides are designed to target and inhibit specific RNA molecules. Additionally, it is utilized in the development of aptamers and for studying nucleic acid interactions in biochemical assays. Its role in creating stable, high-affinity oligonucleotides is crucial for advancing gene silencing technologies and diagnostic tools.
