GalNAc-NAG-37 Phosphoramidite
Quick view. We supply GalNAc-NAG-37 Phosphoramidite as a triantennary GalNAc phosphoramidite for synthesizing GalNAc-conjugated oligonucleotides. CAS 2199491-27-3. Catalog target purity: ≥95%.

Product profile
GalNAc-NAG-37 Phosphoramidite is classified as protected oligonucleotide phosphoramidite building block (Formula C80H127N10O37P; molecular weight 1851.88).
GalNAc-NAG-37 Phosphoramidite can be evaluated as a monomer or functional building block in solid-phase oligonucleotide synthesis.
For GalNAc-NAG-37 Phosphoramidite, in-vitro affinity and in-vivo delivery behavior may diverge; valency, linker length and conjugation site need empirical confirmation.

Release documentation
The current specification defines the analytical method and acceptance criteria; the released lot result is reported on the CoA.
- We release this product against the stated purity specification; the lot-specific CoA provides the result and analytical basis.
Additional HPLC, MS or NMR documentation can be agreed during technical review where available.
Additional application examples
- Typical development work includes coupling-condition screening, deprotection compatibility checks and LC-MS/HPLC characterization of test sequences.
- The material can also support related-analog comparison, impurity-reference preparation and route-development studies.
Product-specific evaluation notes
Potential advantages
- A defined GalNAc intermediate helps decouple ligand-linker optimization from sequence optimization.
Method limitations
- In-vitro affinity and in-vivo delivery behavior may diverge; valency, linker length and conjugation site need empirical confirmation.
