Product profile
Peracetylated GalNAc PEG linker-Azide is classified as galnac (Formula C22H36N4O12; molecular weight 548.55).
Peracetylated GalNAc PEG linker-Azide is useful as a bioorthogonal handle for post-synthetic conjugation to fluorophores, affinity tags, surfaces, peptides or other functional payloads.
For Peracetylated GalNAc PEG linker-Azide, copper-catalyzed, copper-free or inverse-electron-demand click conditions can affect sensitive oligonucleotides differently; residual metal, solvent and purification strategy should be controlled.

Product-specific evaluation notes
Potential advantages
- Click-compatible handles separate oligonucleotide synthesis from late-stage labeling, which helps screen multiple payloads from a common intermediate.
- A defined GalNAc intermediate helps decouple ligand-linker optimization from sequence optimization.
Method limitations
- Copper-catalyzed, copper-free or inverse-electron-demand click conditions can affect sensitive oligonucleotides differently; residual metal, solvent and purification strategy should be controlled.
- In-vitro affinity and in-vivo delivery behavior may diverge; valency, linker length and conjugation site need empirical confirmation.
