5'-O-DMT-2'-O-TBDMS-N4-acetylcytidine is cytidine carrying three protecting groups: a 5'-O-(4,4'-dimethoxytrityl) (DMT) group, a 2'-O-(tert-butyldimethylsilyl) (TBDMS) group, and an N4-acetyl base-protecting group. CH64111 is identified by CAS 121058-85-3, molecular formula C38H47N3O8Si, molecular weight 701.9, PubChem CID 11136250, and InChIKey ZFRWPAYPCFTQHK-HYGOWAQNSA-N.
It is an RNA phosphoramidite precursor: the acid-labile 5'-DMT group is removed at the start of each chain-elongation cycle, the 2'-O-TBDMS group protects the ribose 2'-hydroxyl during RNA synthesis, and the N4-acetyl group masks the cytosine exocyclic amine and is removed at final deprotection.

Anwendungskontext
- 5'-DMT 5'-OH protection: the acid-labile 4,4'-dimethoxytrityl group protects the 5'-hydroxyl and is removed at the start of each RNA chain-elongation cycle.
- 2'-O-TBDMS 2'-OH protection: the tert-butyldimethylsilyl group protects the ribose 2'-hydroxyl during solid-phase RNA synthesis.
- N4-acetyl base protection: the acetyl group masks the cytosine exocyclic amine during synthesis and is removed at final deprotection.

Häufig gestellte Fragen
What do the three protecting groups on this cytidine do?
The 5'-O-DMT group is an acid-labile 5'-hydroxyl protection removed at the start of each RNA chain-elongation cycle; the 2'-O-TBDMS group protects the ribose 2'-hydroxyl during solid-phase RNA synthesis; and the N4-acetyl group protects the cytosine exocyclic amine, removed at final deprotection.
How does it differ from 5'-O-DMT-2'-O-TBDMS-N4-benzoylcytidine?
Both are 5'-O-DMT-2'-O-TBDMS-protected cytidines with a protected cytosine N4-amine, but this one uses an acetyl group rather than benzoyl. The benzoyl form is cataloged separately.
