Quick view. A 5'-O-DMTr- and N2-isobutyryl-protected 3'-O-methylguanosine 2'-O-CED phosphoramidite, CAS 179479-04-0. CAS 179479-04-0. Catalog target purity: ≥98%. Availability: Inquiry only — contact BX Lab to confirm current availability.
Product profile
3'-O-Me-G(iBu)-2'-phosphoramidite is classified as other phosphoramidites (Formula C45H56N7O9P; molecular weight 869.94).
3'-O-Me-G(iBu)-2'-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 3'-O-Me-G(iBu)-2'-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.
