Used in the synthesis of oligonucleotides, it plays a crucial role in the development of RNA-based therapeutics, including antisense oligonucleotides and siRNA. It enhances the stability and binding affinity of RNA molecules, making it valuable in gene silencing and targeted drug delivery. Additionally, it is employed in research to study RNA structure and function, aiding in the understanding of genetic regulation and disease mechanisms. Its modified structure helps improve resistance to nucleases, making it suitable for applications in biotechnology and molecular biology.
