Product profile
Azido-PEG4-beta-D-galactose is classified as intermediates (Formula C14H27N3O9; molecular weight 381.40).
Azido-PEG4-beta-D-galactose is useful as a bioorthogonal handle for post-synthetic conjugation to fluorophores, affinity tags, surfaces, peptides or other functional payloads.
For Azido-PEG4-beta-D-galactose, 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.
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.
