N-Boc-N-bis(PEG2-propargyl)（Cat No.:I014507）is a versatile PEG-based linker offering dual functionality for advanced conjugation strategies. It contains a Boc-protected amine that allows controlled deprotection and subsequent coupling to biomolecules or polymers. The two PEG2-propargyl groups enable efficient click chemistry with azides via copper-catalyzed or strain-promoted reactions, supporting site-specific and orthogonal modifications. The PEG2 spacers enhance solubility, flexibility, and reduce steric hindrance, ensuring compatibility with complex biological systems. This multifunctional reagent is widely applied in drug delivery, diagnostic probe development, chemical biology, and material science for constructing modular, multifunctional conjugates with precision.
