Azido-PEG3-C6-Cl（Cat No.:I044626）is a heterobifunctional PEG linker featuring an azide group and a reactive chloroalkane, connected via a PEG3 spacer and a six-carbon alkyl chain. The azide enables copper-catalyzed azide-alkyne cycloaddition (CuAAC) for site-specific click chemistry, while the chloro group reacts with nucleophiles such as thiols or amines, allowing versatile conjugation strategies. The PEG3 unit imparts water solubility and spatial flexibility, minimizing steric hindrance. This reagent is ideal for bioconjugation, surface modification, and the development of multifunctional biomaterials, especially in drug delivery and diagnostic research applications.
