Azido-PEG9-Boc（Cat No.:I015815）is a multifunctional polyethylene glycol linker designed for versatile bioconjugation. It contains a terminal azide group for copper-catalyzed or strain-promoted click chemistry with alkynes, and a Boc-protected amine that enables orthogonal deprotection and subsequent conjugation. The PEG9 spacer provides hydrophilicity, flexibility, and reduced steric hindrance, ensuring high solubility and efficient reactivity in both aqueous and organic systems. This balanced design supports controlled labeling and modular functionalization. Azido-PEG9-Boc is widely applied in chemical biology, drug discovery, proteomics, and biomaterials research for precise molecular engineering and probe development.
