This compound is primarily used in the synthesis of oligonucleotides, particularly in the field of nucleic acid research and therapeutic development. It serves as a key building block in solid-phase oligonucleotide synthesis, enabling the incorporation of modified guanosine residues into DNA or RNA sequences. The 2'-O-(2-methoxyethyl) modification enhances the stability and nuclease resistance of the resulting oligonucleotides, making it valuable for applications in antisense technology and RNA-based therapeutics. Additionally, the DMT (dimethoxytrityl) group protects the 5'-hydroxy during synthesis, allowing for stepwise elongation of the oligonucleotide chain. Its application is critical in the development of gene silencing drugs, diagnostic probes, and other advanced molecular biology tools.
