Product profile
5'-O-(4,4'-Dimethoxytrityl)-3'-O-methyluridine is classified as protected nucleosides (Formula C31H32N2O8; molecular weight 560.59).
5'-O-(4,4'-Dimethoxytrityl)-3'-O-methyluridine can be evaluated in terminally blocked nucleotide, cap-chemistry and analytical-reference workflows where 3′-O-methylation changes extension or end-group reactivity.
For 5'-O-(4,4'-Dimethoxytrityl)-3'-O-methyluridine, the 3′-O-methyl group blocks normal 3′-hydroxyl extension; confirm that this behavior matches the intended enzyme or synthesis workflow.

Product-specific evaluation notes
Potential advantages
- 3′-O-methylation provides a defined blocked ribose terminus and is analytically distinguishable from the corresponding 2′-O-methyl isomer.
Method limitations
- The 3′-O-methyl group blocks normal 3′-hydroxyl extension; confirm that this behavior matches the intended enzyme or synthesis workflow.
