Bromoacetamido-PEG5-azide（Cat No.:I015789）is a heterobifunctional crosslinker designed for selective and versatile bioconjugation. It features a bromoacetamide group that reacts specifically with thiol residues to form stable thioether bonds, and a terminal azide group suitable for copper-catalyzed or strain-promoted click chemistry with alkynes. The PEG5 spacer provides hydrophilicity, flexibility, and reduced steric hindrance, ensuring excellent solubility and reactivity in aqueous and organic systems. This dual-functional reagent is widely employed in proteomics, chemical biology, probe development, and drug discovery, enabling site-specific labeling, modular assembly, and multifunctional biomolecular engineering applications.
