5'-Me-(E)-vinyl phosphonate-3'-O-Me-rG
Quick view. A guanine ribonucleoside analog bearing a 3'-O-methyl group, a free 2'-hydroxyl group and an E-vinyl phosphonate dimethyl ester at the 5' side. A public CAS number is not assigned for this exact form. Catalog target purity: ≥98%. Availability: Inquiry only — contact BX Lab to confirm current availability.
Product profile
5'-Me-(E)-vinyl phosphonate-3'-O-Me-rG is classified as other modified nucleosides (Formula C14H20N5O7P; molecular weight 401.32).
5'-Me-(E)-vinyl phosphonate-3'-O-Me-rG 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'-Me-(E)-vinyl phosphonate-3'-O-Me-rG, 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.
