2'-O-TBDMS-Inosine CE Phosphoramidite is the inosine building block for RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-2'-O-(tert-butyldimethylsilyl)-inosine (hypoxanthine base) bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65016 is identified by CAS 261518-12-1, molecular formula C46H61N6O8PSi, molecular weight 885.1, PubChem CID 135483567, and InChIKey ZUFMOUFQBYZIHB-JFOZTMRSSA-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, and the 2'-O-TBDMS protects the ribose 2'-hydroxyl. Because the hypoxanthine base has no exocyclic amine, no base protecting group is required.

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.
- No base protection needed: the hypoxanthine base has no exocyclic amine, so this monomer requires no base protecting group.

Preguntas frecuentes
Why does the inosine RNA 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), the 2'-O-TBDMS group (protects the ribose 2'-hydroxyl), and the 3'-phosphoramidite coupling group.
How does it differ from the 2'-deoxyinosine phosphoramidite?
This is the ribonucleoside (RNA) form with a 2'-O-TBDMS-protected 2'-hydroxyl, whereas the 2'-deoxyinosine amidite has no 2'-OH. The 2'-deoxyinosine amidite is cataloged separately.
