Product Introduction

Azido-PEG3-amine is a bifunctional reagent featuring an azide group and a primary amine, which facilitates its role in click chemistry and bioconjugation applications. The azide functionality participates in copper-catalyzed azide–alkyne cycloaddition (CuAAC) and strain-promoted azide–alkyne cycloaddition (SPAAC), enabling efficient conjugation with alkyne-bearing molecules. Its polyethylene glycol (PEG) spacer provides aqueous solubility and flexibility, making it suitable for linker design, surface modification, and polymer functionalization in diverse experimental contexts.
