Azido-PEG9-azide (Cat No.: I016264) is a bifunctional polyethylene glycol (PEG) linker with two terminal azide (-N₃) groups. Its nine-unit PEG spacer provides high water solubility, flexibility, and biocompatibility, making it ideal for bioconjugation, drug delivery, and click chemistry applications. The azide groups enable selective reactions with alkynes via copper-catalyzed azide-alkyne cycloaddition (CuAAC) or strain-promoted cycloaddition, facilitating the synthesis of complex biomolecules, nanoparticles, and hydrogels. This linker is widely used in biomedical research, material science, and targeted drug development.
