N-(Azido-PEG2)-N-bis(PEG4-Boc)（Cat No.:I015756）is a multifunctional PEG-based linker tailored for flexible bioconjugation and molecular design. It incorporates a terminal azide group for efficient click chemistry with alkynes, while two PEG4 chains terminate in Boc-protected amines, enabling orthogonal deprotection and further functionalization under mild conditions. The PEG2 and PEG4 spacers impart hydrophilicity, flexibility, and solubility, while reducing steric hindrance in complex systems. This branched architecture makes the reagent highly suitable for constructing multifunctional probes, biomaterials, and drug conjugates, providing precise control for applications in chemical biology and advanced therapeutic research.
