2'-dA (Bz) 3'-Succinate, Triethylammonium Salt is a support-loading precursor for oligonucleotide synthesis: 5'-O-(4,4'-dimethoxytrityl)-N6-benzoyl-2'-deoxyadenosine 3'-O-succinate, present as its triethylammonium salt. Its PubChem-backed identity includes CAS 402944-15-4, molecular formula C48H54N6O9, molecular weight 859.0, and PubChem CID 138375999.
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 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; the 5'-DMT protects the 5'-hydroxyl and the N6-benzoyl group the adenine amine.

应用背景
- 3'-terminal support loading: the 3'-O-succinate couples to an amino-functionalized solid support to immobilize the 3'-terminal dA(Bz) residue.
- Base-cleavable linker: the succinyl ester is cleaved during deprotection, releasing the finished oligonucleotide from the support.
- Standard protection: the 5'-DMT protects the 5'-hydroxyl (removed to start the first coupling) and the N6-benzoyl group protects the adenine amine.

常见问题
Is this a phosphoramidite?
No. It is a nucleoside 3'-O-succinate (a support-loading precursor), not a phosphoramidite. Its 3'-succinate half-ester is used to attach the 3'-terminal nucleoside to a solid support before chain assembly begins.
What is the succinate linker for?
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.
