2'-OMe-Adenosine (Bz) CE Phosphoramidite is the 2'-O-methyl adenosine building block for modified-RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-N6-benzoyl-2'-O-methyladenosine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65017 is identified by CAS 110782-31-5, molecular formula C48H54N7O8P, molecular weight 888.0, PubChem CID 13872235, and InChIKey AZCGOTUYEPXHMJ-PSVHYZMASA-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 N6-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.

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 literature discusses 2'-O-methyl residues in relation to nuclease resistance and RNA affinity.
  • 5'-DMT + N6-benzoyl protection: the acid-labile 5'-DMT is removed each cycle, and the N6-benzoyl base group is removed at final deprotection.

よくある質問

How does it relate to 5'-O-DMT-N6-benzoyl-2'-O-methyladenosine?

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.
