2'-O-TBDMS-A (Bz) 3'-PS Thiophosphoramidite is a phosphorothioate-linkage RNA building block: a 5'-O-(4,4'-dimethoxytrityl)-N6-benzoyl-2'-O-(tert-butyldimethylsilyl)adenosine 3'-thiophosphoramidite. It is identified by CAS 1374755-65-3, molecular formula C57H65N6O8PS2Si, molecular weight 1085.4, PubChem CID 102308172, and InChIKey ALJIYXCITZABFP-WOMFGPHHSA-N.
As a thiophosphoramidite it provides the sulfur-bearing phosphorus chemistry used for phosphorothioate (PS) linkage synthesis. The cited phosphorothioate literature discusses PS linkages in relation to nuclease resistance. The 2'-O-TBDMS group is the silyl protecting group for the 2'-hydroxyl in RNA synthesis; the 5'-DMT is removed each cycle and the N6-benzoyl base-protecting group is removed during final deprotection.

Questions fréquentes
How does this differ from the standard 2'-O-TBDMS-rA(Bz) amidite?
It is a thiophosphoramidite rather than a standard phosphoramidite: the phosphorus chemistry is used for phosphorothioate (PS) linkage synthesis, whereas the standard amidite is used for phosphodiester linkage synthesis. Both carry 5'-DMT, 2'-O-TBDMS, and N6-benzoyl protection.
