Product profile
3'-OMe-m7GDP TEA Salt is classified as intermediates (Formula C12H19N5O11P2; molecular weight 471.26).
3'-OMe-m7GDP TEA Salt 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'-OMe-m7GDP TEA Salt, 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.
- Cap analog selection can influence capping efficiency, orientation and downstream translation-related performance.
Method limitations
- The 3′-O-methyl group blocks normal 3′-hydroxyl extension; confirm that this behavior matches the intended enzyme or synthesis workflow.
- Capping outcome depends on polymerase system, cap-to-NTP ratio, transcript design and purification method.
