N3-PEG2-Tos is an azide-terminated PEG2 tosylate linker used as a synthetic building block for organic synthesis and bioconjugation. The tosylate is a good leaving group for nucleophilic substitution, and the azide serves as a click-chemistry handle for rapid, selective conjugation under copper-catalyzed conditions.
- Azide functional group for copper-catalyzed azide-alkyne cycloaddition.
- Tosylate leaving group enables efficient nucleophilic substitution.
- Short PEG2 spacer provides flexibility and improved solubility in common organic solvents.
- High reported purity supports consistent reaction performance.
