Bis-propargyl-PEG5 features two propargyl groups flanking a five-unit polyethylene glycol chain, enabling efficient dual-click functionalization in bioconjugation and materials assembly. This bifunctional linker combines excellent solubility with robust stability under standard reaction conditions.
Bis-propargyl-PEG5 serves as a versatile, bifunctional building block for click chemistry and polymer conjugation. Its two terminal propargyl groups enable efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC), facilitating the construction of well-defined macromolecular architectures. The PEG5 spacer provides enhanced solubility and biocompatibility, while the molecule exhibits excellent bench stability and ease of purification—ideal for synthesizing bioconjugates, drug delivery systems, and functionalized surfaces.
