2'-OMe-Uridine CE Phosphoramidite is the 2'-O-methyl uridine building block for modified-RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-2'-O-methyluridine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65020 is identified by CAS 110764-79-9, molecular formula C40H49N4O9P, molecular weight 760.8, PubChem CID 10897989, and InChIKey UVUOJOLPNDCIHL-XKZJCBTISA-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 uracil 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.

用途情報

  • 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: uracil has no exocyclic amine, so this monomer requires no base protecting group (only the acid-labile 5'-DMT, removed each cycle).

よくある質問

Why does the 2'-OMe-uridine phosphoramidite have no base protecting group?

Uracil 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-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.
