GalNAc-L96-Succinate, Triethylammonium Salt is a conjugate support-loading precursor for oligonucleotide synthesis: a triantennary (trivalent) N-acetylgalactosamine ("GalNAc", L96) cluster joined to a succinate half-ester, supplied as its triethylammonium salt. Key identifiers include CAS 1159408-62-4, molecular formula C127H194N12O45, and molecular weight 2608.9 (PubChem CID 168006875).
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 a 3'-terminal unit — here the GalNAc cluster — to an amino-functionalized solid support, so the oligonucleotide is then assembled carrying the GalNAc ligand at its 3'-end. The succinyl linkage is base-cleavable and is broken during deprotection to release the finished conjugate. Triantennary GalNAc binds the asialoglycoprotein receptor (ASGPR), a lectin on the surface of hepatocytes.

Frequently Asked Questions
Is this a phosphoramidite?
No. It is a GalNAc-cluster 3'-O-succinate (a conjugate support-loading precursor), not a phosphoramidite. Its succinate half-ester attaches the triantennary GalNAc ligand to a solid support so the oligonucleotide is built carrying the GalNAc at its 3'-end.
What is a triantennary GalNAc cluster, and what does it bind?
It is a trivalent presentation of N-acetylgalactosamine (three GalNAc sugars on a branched scaffold). Triantennary GalNAc binds the asialoglycoprotein receptor (ASGPR), a lectin on the surface of hepatocytes.
