2'-O-Propargyl-A (Bz) CE Phosphoramidite is a click-handle RNA building block: 5'-O-(4,4'-dimethoxytrityl)-N6-benzoyl-2'-O-(prop-2-yn-1-yl)adenosine 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite. It is identified by CAS 171486-59-2, molecular formula C50H54N7O8P, molecular weight 912.0, PubChem CID 102119200, and InChIKey ZNKFQCJEZKZIPC-XOMUZYEBSA-N.
The 2'-O-propargyl group is a permanent 2'-O-ether that carries a terminal alkyne (C≡CH) — it is not a protecting group. That terminal alkyne is a "click" handle: oligonucleotides bearing a terminal alkyne can be labeled after synthesis by the copper-catalyzed azide-alkyne cycloaddition (CuAAC) with azide-bearing reporters. The monomer couples through a standard 3'-phosphoramidite (3'→5' linkages), the 5'-DMT is removed each cycle, and the N6-benzoyl base group is removed at final deprotection.

应用背景
- Internal click handle: the 2'-O-propargyl ether places a terminal alkyne at the 2'-position for post-synthetic conjugation.
- CuAAC labeling: the terminal alkyne reacts with azide-bearing reporters (dyes, biotin, other tags) by the copper-catalyzed azide-alkyne cycloaddition (click chemistry).
- 3'→5' coupling monomer: the 3'-phosphoramidite couples to form 3'→5' linkages; the 5'-DMT is removed each cycle and the N6-benzoyl base-protecting group is removed during final deprotection.

常见问题
What does the 2'-O-propargyl group provide?
It is a permanent 2'-O-ether that carries a terminal alkyne. The alkyne is a 'click' handle: after synthesis, the oligonucleotide can be conjugated to azide-bearing reporters (dyes, biotin, etc.) by the copper-catalyzed azide-alkyne cycloaddition (CuAAC).
Is the propargyl group a protecting group that gets removed?
No. Unlike the 5'-DMT (removed each cycle) or the N6-benzoyl base group (removed at final deprotection), the 2'-O-propargyl ether is a permanent modification that stays on the finished oligonucleotide as the click handle.
