Azido-PEG9-alcohol（Cat No.:I015806）is a heterobifunctional polyethylene glycol derivative designed for versatile bioconjugation. It carries a terminal azide group that participates in copper-catalyzed or strain-promoted click chemistry with alkynes, and a hydroxyl group that can be further functionalized through esterification, etherification, or carbamate formation. The PEG9 spacer provides hydrophilicity, flexibility, and reduced steric hindrance, ensuring high solubility and accessibility in both aqueous and organic environments. This reagent is widely used in probe development, biomaterials, proteomics, and drug delivery, enabling modular assembly, site-specific labeling, and advanced molecular engineering strategies.
