Product profile
3'-O-Methylcytidine is classified as modified nucleosides (Formula C10H15N3O5; molecular weight 257.24 g/mol).
3'-O-Methylcytidine can be evaluated in terminally blocked nucleotide, cap-chemistry and analytical-reference workflows where 3′-O-methylation changes extension or end-group reactivity.
For 3'-O-Methylcytidine, 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.
