5'-O-DMT-N4-benzoyl-2'-deoxycytidine is 2'-deoxycytidine carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group and an N4-benzoyl base-protecting group. CH64100 is identified by CAS 67219-55-0, molecular formula C37H35N3O7, molecular weight 633.69, PubChem CID 2724490, and InChIKey MYSNCIZBPUPZMQ-VOTWKOMSSA-N.
It is a doubly protected precursor for DNA phosphoramidite/oligonucleotide synthesis: the acid-labile 5'-DMT group is removed at the start of each chain-elongation cycle, while the N4-benzoyl group masks the cytosine exocyclic amine and is removed at final deprotection.

자주 묻는 질문
What do the two protecting groups on this deoxycytidine do?
The 5'-O-DMT (dimethoxytrityl) group is an acid-labile protection on the 5'-hydroxyl that is removed at the start of each oligonucleotide chain-elongation cycle; the N4-benzoyl group protects the cytosine exocyclic amine during synthesis and is removed at final deprotection.
How does it differ from N4-benzoyl-2'-deoxycytidine?
Both carry an N4-benzoyl-protected cytosine, but this one also has a 5'-O-DMT group on the 5'-hydroxyl. N4-benzoyl-2'-deoxycytidine (without DMT) is cataloged separately.
