2'-F-Cytidine (Bz) CE Phosphoramidite is the 2'-fluoro cytidine building block for modified-RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-2'-fluoro-N4-benzoyl-2'-deoxycytidine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65027 is identified by CAS 161442-19-9, molecular formula C46H51FN5O8P, molecular weight 851.9, PubChem CID 10328204, and InChIKey CKKJPMGSTGVCJJ-GNUWXFRUSA-N.

Nucleoside phosphoramidites are the coupling monomers used in automated solid-phase oligonucleotide synthesis: the 3'-phosphoramidite couples to the growing chain, the acid-labile 5'-DMT is removed each cycle, and the N4-benzoyl base group is removed at final deprotection. The cited oligonucleotide literature discusses 2'-fluoro modifications in relation to RNA affinity and nuclease resistance.

Application context

  • 2'-F 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 synthesis.
  • 2'-Fluoro sugar modification: cited oligonucleotide literature discusses 2'-fluoro modifications in relation to RNA affinity and nuclease resistance.
  • 5'-DMT + N4-benzoyl protection: the acid-labile 5'-DMT is removed each cycle, and the N4-benzoyl base group is removed at final deprotection.

Frequently Asked Questions

What does this 2'-F amidite do in RNA synthesis?

Its 3'-phosphoramidite couples to the growing chain, with 5'-DMT removed each cycle and N4-benzoyl removed at final deprotection. The product provides a 2'-fluoro cytidine phosphoramidite identity.

How does it relate to 5'-O-DMT-2'-fluoro-N4-benzoyl-2'-deoxycytidine?

It is the phosphoramidite of that nucleoside: the 3'-hydroxyl has been converted to a 2-cyanoethyl N,N-diisopropyl phosphoramidite. The precursor is cataloged separately.

What identifiers should match for CH65027?

Match CAS 161442-19-9, molecular formula C46H51FN5O8P, molecular weight 851.9, PubChem CID 10328204, and InChIKey CKKJPMGSTGVCJJ-GNUWXFRUSA-N.
