2'-O-TBDMS-rA (Bz) 3'-Succinate, Triethylammonium Salt is a support-loading precursor for RNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-N6-benzoyl-2'-O-(tert-butyldimethylsilyl)-adenosine 3'-O-succinate, listed as its triethylammonium salt. Its PubChem-backed succinate identity includes CAS 131316-88-6, molecular formula C48H53N5O10Si, molecular weight 888.0, and PubChem CID 102316472.

Unlike a phosphoramidite, this reagent carries a 3'-O-succinate half-ester rather than a coupling group. The succinate is the conventional linker for attaching the 3'-terminal RNA nucleoside to an amino-functionalized solid support (such as controlled-pore glass), so that chain assembly starts from this residue. The succinyl linkage is base-cleavable and is broken during deprotection to release the finished oligonucleotide; 2'-O-TBDMS protects the 2'-hydroxyl, 5'-DMT protects the 5'-hydroxyl, and N6-benzoyl protects the adenine amine.

Anwendungskontext

  • 3'-terminal RNA support loading: the 3'-O-succinate couples to an amino-functionalized solid support to immobilize the 3'-terminal 2'-O-TBDMS-rA(Bz) residue.
  • Base-cleavable linker: the succinyl ester is cleaved during deprotection, releasing the finished oligonucleotide from the support.
  • Standard RNA protection: 2'-O-TBDMS protects the 2'-hydroxyl, 5'-DMT protects the 5'-hydroxyl, and N6-benzoyl protects the adenine amine.

Häufig gestellte Fragen

Is this a phosphoramidite?

No. It is a 2'-O-TBDMS RNA nucleoside 3'-O-succinate (a support-loading precursor), not a phosphoramidite. Its 3'-succinate half-ester attaches the 3'-terminal RNA residue to a solid support before chain assembly begins.

What is the succinate linker for, and is it cleaved?

The succinate couples the nucleoside to an amino-functionalized solid support (e.g. controlled-pore glass). It is a base-cleavable ester, so it is broken during deprotection to release the finished oligonucleotide.
