Used primarily in the synthesis of modified nucleosides, this chemical serves as a key intermediate in the development of oligonucleotides for research and therapeutic applications. Its protective groups, specifically the tetraisopropyldisiloxane moiety, shield the hydroxyl groups during chemical reactions, ensuring selective modification of the nucleoside. This compound is particularly valuable in the production of antisense oligonucleotides and siRNA, which are crucial in gene silencing and targeted therapy for various diseases, including cancer and genetic disorders. Additionally, it plays a role in the study of RNA structure and function, aiding in the advancement of molecular biology and drug discovery.
