5'-O-DMT-2'-fluoro-N4-acetyl-2'-deoxycytidine is 2'-fluoro-2'-deoxycytidine carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group and an N4-acetyl base-protecting group. CH64124 is identified by CAS 159414-98-9, molecular formula C32H32FN3O7, molecular weight 589.6, PubChem CID 22094553, and InChIKey JIFNUYITABZZQS-PYYPWFDZSA-N.
It is a 2'-F-modified RNA phosphoramidite precursor context: the acid-labile 5'-DMT group is removed at the start of each chain-elongation cycle, and the N4-acetyl group masks the cytosine exocyclic amine and is removed at final deprotection. The cited oligonucleotide literature discusses 2'-fluoro modifications in relation to RNA affinity and nuclease resistance.

Application context
- 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'-Fluoro sugar modification: cited oligonucleotide literature discusses 2'-fluoro modifications in relation to RNA affinity and nuclease resistance.
- N4-acetyl base protection: the acetyl group masks the cytosine exocyclic amine during synthesis and is removed at final deprotection.

Frequently Asked Questions
How does it differ from N4-acetyl-2'-fluoro-2'-deoxycytidine?
Both carry an N4-acetyl-protected 2'-fluoro cytidine, but this one also has a 5'-O-DMT group on the 5'-hydroxyl (as a phosphoramidite precursor). The non-DMT form is cataloged separately.
