5'-O- (4,4'-Dimethoxytrityl) -2'-O- (2-methoxyethyl) adenosine

These are protected nucleoside derivatives with free amino and hydroxyl groups, suitable for oligonucleotide synthesis and medicinal chemistry research. They serve as key intermediates in the development of nucleotide analogs for in vitro biochemical studies and in vivo therapeutic applications, such as antiviral and anticancer agent development.
