Propynyl-PEG1-Ac features a reactive terminal alkyne paired with a short, hydrophilic PEG spacer and acetyl protection. This combination enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) while maintaining solubility in aqueous and organic media. The acetyl group stabilizes the propynyl moiety against premature reaction, offering controlled bioconjugation under standard conditions.
Propynyl-PEG1-Ac enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) for bioconjugation and polymer functionalization. Its terminal alkyne group exhibits excellent stability, compatibility with diverse functional groups, and facilitates straightforward purification via standard chromatographic methods. This reagent serves as a versatile building block for constructing well-defined PEGylated architectures in drug delivery and materials science applications.
