2'-OMe-Guanosine (dmf) CE Phosphoramidite is the 2'-O-methyl guanosine building block for modified-RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-N2-dimethylformamidine-2'-O-methylguanosine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65021 is identified by CAS 128219-77-2, molecular formula C44H55N8O8P, molecular weight 854.9, PubChem CID 135742510, and InChIKey ZGDBCILCTOHNAB-OWKWDSSOSA-N.
Nucleoside phosphoramidites are the coupling monomers used in automated solid-phase oligonucleotide synthesis: the 3'-phosphoramidite couples to the growing chain, the acid-labile 5'-DMT is removed each cycle, and the N2-dmf base group is removed at final deprotection. In the cited literature, 2'-O-methyl ribonucleosides/residues are discussed for nuclease resistance and RNA affinity.

Preguntas frecuentes
What does this 2'-OMe amidite do in RNA synthesis?
Its 3'-phosphoramidite couples to the growing chain, with 5'-DMT removed each cycle and N2-dmf removed at final deprotection. The product provides a 2'-O-methylguanosine phosphoramidite identity.
How does it differ from the 2'-OMe-G(iBu) phosphoramidite?
Both are 2'-O-methyl guanosine amidites, but this one uses an N2-dimethylformamidine (dmf) base protection rather than isobutyryl. The isobutyryl amidite is cataloged separately.
