2'-OMe-Cytidine (Bz) CE Phosphoramidite is the 2'-O-methyl cytidine building block for modified-RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-N4-benzoyl-2'-O-methylcytidine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65023 is identified by CAS 110764-78-8, molecular formula C47H54N5O9P, molecular weight 863.9, PubChem CID 13872225, and InChIKey JFFSFQRVIPPCBC-VKBHKTMGSA-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 N4-benzoyl base group is removed at final deprotection. In the cited literature, 2'-O-methyl ribonucleosides/residues are discussed for nuclease resistance and RNA affinity.

よくある質問

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 N4-benzoyl removed at final deprotection. The product provides a 2'-O-methylcytidine phosphoramidite identity.

How does it differ from the 2'-OMe-C(Ac) phosphoramidite?

Both are 2'-O-methyl cytidine amidites, but this one uses an N4-benzoyl base protection rather than acetyl. The acetyl amidite is cataloged separately.
