Azido-PEG2-C6-Cl（Cat No.:I044624）is a heterobifunctional PEG linker featuring an azide group and a reactive alkyl chloride moiety separated by a PEG2 spacer and a six-carbon alkyl chain. The azide group enables bioorthogonal click chemistry via copper-catalyzed azide-alkyne cycloaddition (CuAAC), while the chloro group reacts with nucleophiles such as amines or thiols for covalent attachment. This versatile reagent enhances solubility, flexibility, and spatial separation in bioconjugation, drug delivery, and surface modification applications, especially for site-specific labeling of biomolecules or preparing multifunctional polymers and nanoparticles.
