Widely used in the synthesis of oligonucleotides, especially in the preparation of modified RNA strands for research and therapeutic applications. The 2'-O-TBDMS group provides stability by protecting the ribose 2'-hydroxyl during solid-phase synthesis, while the DMT group at the 5' end allows for monitoring and purification during each coupling step. The phosphoramidite functionality enables efficient and precise addition to the growing nucleotide chain through automated DNA/RNA synthesizers. This compound is particularly valuable in the production of antisense oligonucleotides, siRNA, and other nucleic acid-based drugs where controlled modification enhances nuclease resistance and target binding affinity. Its use supports high-yield, stepwise assembly of complex sequences used in molecular biology, genomics, and drug development.
