N3-PEG2-Tos is an azide-terminated PEG2 linker bearing a tosylate leaving group. It is designed as a small, bifunctional spacer for organic synthesis and bioconjugation: the azide provides a click-chemistry handle for azide-alkyne cycloadditions, while the tosylate permits nucleophilic substitution to introduce other functional groups.

• Azide functional group enables click chemistry conjugation.
• Tosylate leaving group allows facile nucleophilic substitution.
• Short PEG2 spacer provides flexibility and solubility.
• High purity suitable for synthetic and assay applications.
• Available as a 1 g solid for small-scale synthesis.
• Molecular weight ~285.3 g·mol⁻¹ for stoichiometry calculations.
