2'-OMe-5-Methyluridine CE Phosphoramidite is the 2'-O-methyl 5-methyluridine building block for modified-RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-2'-O-methyl-5-methyluridine (5-methyluracil base) bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65025 is identified by CAS 153631-20-0, molecular formula C41H51N4O9P, molecular weight 774.8, PubChem CID 10327870, and InChIKey GMJRPRHRYILEOK-VNZAIEIISA-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 5-methyluracil 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.

Contexto de aplicación
- 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 5-methyluracil base has no exocyclic amine, so this monomer requires no base protecting group (only the acid-labile 5'-DMT, removed each cycle).

Preguntas frecuentes
Why does this 2'-OMe amidite have no base protecting group?
Its base is 5-methyluracil, which 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 relate to 5'-O-DMT-5-methyl-2'-O-methyluridine?
It is the phosphoramidite of that nucleoside: the 3'-hydroxyl has been converted to a 2-cyanoethyl N,N-diisopropyl phosphoramidite. The precursor is cataloged separately.
