2'-O-MOE-Cytidine (Bz) CE Phosphoramidite is the 2'-O-methoxyethyl cytidine building block for modified-RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-2'-O-(2-methoxyethyl)-N4-benzoylcytidine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65037 is identified by CAS 251647-54-8, molecular formula C49H58N5O10P, molecular weight 908.0, PubChem CID 127262586, and InChIKey IAFVTVZPQIFRAU-NXPFYNPLSA-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 structure and stability literature, 2'-O-MOE ribonucleosides/residues are discussed in RNA-affinity and nuclease-resistance studies and as flanking residues in gapmer antisense oligonucleotides.

Frequently Asked Questions
What does this 2'-MOE 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-methoxyethyl cytidine phosphoramidite identity.
How does it differ from the 2'-O-MOE-5-Me-C(Bz) phosphoramidite?
Both are N4-benzoyl-protected 2'-MOE cytidine amidites, but that one has a 5-methylcytosine base while this one has a plain cytosine base. The 5-methyl form is cataloged separately.
