Propargyl-PEG24-amine（Cat No.:I014596）is a long, flexible heterobifunctional linker designed for advanced bioconjugation and material science applications. It features a terminal propargyl group for efficient copper-catalyzed or strain-promoted click reactions with azides, alongside a primary amine that couples readily with activated esters or carboxylic acids. The extended PEG24 spacer provides exceptional aqueous solubility, high flexibility, and minimized steric hindrance, making it ideal for complex biological systems. This reagent is widely applied in drug delivery, imaging probe development, chemical biology, and multifunctional conjugate synthesis where long, hydrophilic linkers are required.
