2'-OMe-Inosine CE Phosphoramidite is the 2'-O-methyl inosine building block for modified-RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-2'-O-methylinosine (hypoxanthine base) bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65022 is identified by CAS 128219-85-2, molecular formula C41H49N6O8P, molecular weight 784.8, PubChem CID 135742511, and InChIKey PVFNTYBGWVZMCX-HLHZJIEZSA-N.
Nucleoside phosphoramidites are the coupling monomers used in automated solid-phase oligonucleotide synthesis: the 3'-phosphoramidite couples to the growing chain and the acid-labile 5'-DMT is removed each cycle. Because the hypoxanthine base has no exocyclic amine, no base protecting group is required. In the cited literature, 2'-O-methyl ribonucleosides/residues are discussed for nuclease resistance and RNA affinity.

응용 맥락
- 2'-OMe RNA coupling monomer: the 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite is the reactive group that couples to the growing oligonucleotide chain in automated solid-phase synthesis.
- 2'-OMe sugar modification: cited 2'-O-methyl oligonucleotide literature discusses nuclease resistance and RNA affinity.
- No base protection needed: the hypoxanthine base has no exocyclic amine, so this monomer requires no base protecting group (only the acid-labile 5'-DMT, removed each cycle).

자주 묻는 질문
Why does the 2'-OMe-inosine phosphoramidite have no base protecting group?
The hypoxanthine base of inosine has no reactive exocyclic amine, so it needs no base protection. The monomer carries the acid-labile 5'-O-DMT group, removed each cycle, and the 3'-phosphoramidite coupling group.
How does it differ from the 2'-O-TBDMS-inosine phosphoramidite?
This one has a 2'-O-methyl modification (a permanent methyl on the 2'-oxygen), whereas the 2'-O-TBDMS form protects the 2'-hydroxyl with a silyl group that is later removed. The 2'-O-TBDMS form is cataloged separately.
