Product profile
2'-O-DMTr-N2-isobutyroyl-3'-O-methylguanosine 5'-CE phosphoramidite is classified as other phosphoramidites (Formula C45H56N7O9P; molecular weight 869.96 g/mol).
2'-O-DMTr-N2-isobutyroyl-3'-O-methylguanosine 5'-CE phosphoramidite can be evaluated in terminally blocked nucleotide, cap-chemistry and analytical-reference workflows where 3′-O-methylation changes extension or end-group reactivity.
For 2'-O-DMTr-N2-isobutyroyl-3'-O-methylguanosine 5'-CE phosphoramidite, 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.
