2'-O-TBDMS-Guanosine (dmf) CE Phosphoramidite is the fully protected guanosine building block for RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-2'-O-(tert-butyldimethylsilyl)-N2-dimethylformamidine-guanosine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65015 is identified by CAS 149559-87-5, molecular formula C49H67N8O8PSi, molecular weight 955.2, and supplier-resolved stereochemical InChIKey RQXRLANMGPTUJP-MVEMIKKVSA-N.

Nucleoside phosphoramidites are the coupling monomers used in automated solid-phase RNA synthesis: the 3'-phosphoramidite is the reactive group that couples to the growing chain, the acid-labile 5'-DMT is removed at the start of each cycle, the 2'-O-TBDMS protects the ribose 2'-hydroxyl, and the N2-dmf base group is removed at final deprotection.

Contexto de aplicación

  • 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 RNA synthesis.
  • 5'-DMT + 2'-O-TBDMS protection: the acid-labile 5'-DMT is removed each cycle, while the 2'-O-TBDMS group protects the ribose 2'-hydroxyl during synthesis.
  • N2-dmf base protection: the dimethylformamidine group masks the guanine exocyclic amine during synthesis and is removed at final deprotection.

Preguntas frecuentes

What are the four functional groups on this RNA amidite?

A 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite (the reactive coupling group), an acid-labile 5'-O-DMT group (removed each cycle), a 2'-O-TBDMS group (protects the ribose 2'-hydroxyl), and an N2-dimethylformamidine (dmf) base protection (removed at final deprotection).

How does it differ from the 2'-O-TBDMS-rG(iBu) phosphoramidite?

Both are 2'-O-TBDMS guanosine RNA amidites, but this one uses an N2-dimethylformamidine (dmf) base protection rather than isobutyryl. The isobutyryl amidite is cataloged separately.
