Propargyl-PEG3-alcohol offers a hydrophilic, linear PEG spacer with terminal alkyne and hydroxyl functionalities. This bifunctional scaffold enables site-specific conjugation via copper-catalyzed azide-alkyne cycloaddition while maintaining solubility in aqueous and organic media. Ideal for bioconjugation and polymer functionalization workflows.
Propargyl-PEG3-alcohol serves as a versatile bifunctional linker for conjugation and polymer synthesis, combining the reactivity of a terminal alkyne with a hydrophilic PEG3 spacer and a primary alcohol. It enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) while offering improved solubility and reduced aggregation in aqueous environments. The pendant hydroxyl group facilitates further derivatization or immobilization, making it ideal for bioconjugation, surface functionalization, and modular synthesis of responsive materials.
