Azido-PEG2-C2-Boc（Cat No.:I015819）is a compact heterobifunctional linker designed for precise and efficient bioconjugation. It features a terminal azide group for copper-catalyzed or strain-promoted click chemistry with alkynes, and a Boc-protected amine connected via a C2 spacer, allowing orthogonal deprotection and subsequent functionalization. The PEG2 chain provides hydrophilicity, flexibility, and minimized steric hindrance, ensuring solubility and accessibility in both aqueous and organic systems. This reagent is widely applied in chemical biology, proteomics, biomaterials, and drug discovery, enabling modular assembly, site-specific labeling, and multifunctional molecular engineering in complex biological environments.
