2'-O-TBDMS-Cytidine (Ac) CE Phosphoramidite is the fully protected cytidine building block for RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-2'-O-(tert-butyldimethylsilyl)-N4-acetylcytidine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65011 is identified by CAS 121058-88-6, molecular formula C47H64N5O9PSi, molecular weight 902.1, PubChem CID 11814945, and InChIKey QKWKXYVKGFKODW-YOEDQOPESA-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 N4-acetyl base group is removed at final deprotection.

응용 맥락
- 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.
- N4-acetyl base protection: the acetyl group masks the cytosine exocyclic amine during synthesis and is removed at final deprotection.

자주 묻는 질문
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 N4-acetyl base protection (removed at final deprotection).
How does it differ from the 2'-O-TBDMS-rC(Bz) phosphoramidite?
Both are 2'-O-TBDMS cytidine RNA amidites, but this one uses an N4-acetyl base protection rather than benzoyl. The benzoyl amidite is cataloged separately.
