N-(Boc-PEG1)-N-bis(PEG2-propargyl)（Cat No.:I014508）is a multifunctional PEG-based linker engineered for controlled and orthogonal conjugation strategies. It features a Boc-protected amine that can be selectively deprotected for further coupling, while two terminal propargyl groups enable efficient click chemistry with azides under copper-catalyzed or strain-promoted conditions. The PEG1 and PEG2 spacers improve aqueous solubility, reduce steric hindrance, and provide flexibility in complex conjugation systems. This versatile architecture makes the reagent highly valuable for chemical biology, drug delivery research, diagnostic probe construction, and multifunctional conjugate synthesis requiring precision and modular assembly.
