2'-Deoxycytidine (Ac) CE Phosphoramidite is the fully protected 2'-deoxycytidine building block for DNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-N4-acetyl-2'-deoxycytidine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65005 is identified by CAS 154110-40-4, molecular formula C41H50N5O8P, molecular weight 771.8, PubChem CID 70700205, and InChIKey MECWEBCHRKVTNV-RLWDVSNXSA-N.
Nucleoside phosphoramidites are the coupling monomers used in automated solid-phase oligonucleotide 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 N4-acetyl base group is removed at final deprotection.

응용 맥락
- DNA 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.
- 5'-DMT 5'-OH protection: the acid-labile 4,4'-dimethoxytrityl group is removed at the start of each chain-elongation cycle.
- N4-acetyl base protection: the acetyl group masks the cytosine exocyclic amine during synthesis and is removed at final deprotection.

자주 묻는 질문
What makes this a phosphoramidite building block?
It carries a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group — the reactive coupling group used in automated solid-phase DNA synthesis. It also has an acid-labile 5'-O-DMT group (removed each cycle) and an N4-acetyl base protection (removed at final deprotection).
How does it differ from 2'-deoxycytidine (Bz) phosphoramidite?
Both are 5'-O-DMT 2'-deoxycytidine phosphoramidites, but this one uses an N4-acetyl base protection rather than benzoyl. The benzoyl amidite is cataloged separately.
