5'-O-DMT-2'-deoxy-2'-fluoro-β-D-arabinouridine

This compound is a 2'-fluoro-modified arabinonucleoside derivative, protected with a dimethoxytrityl (DMT) group at the 5'-position while leaving the amino and hydroxyl groups available for further chemical synthesis. It serves as a critical building block in oligonucleotide synthesis for antisense and siRNA research, enabling the study of RNA targeting and modulation in both in vitro and in vivo experimental models.
