Propargyl-PEG3-acid is a PEG-based bifunctional linker featuring a terminal propargyl (alkyne) group and a carboxylic acid; it is used as a non-cleavable three-unit PEG linker for antibody-drug conjugates and as a PEG linker for PROTACs, enabling copper-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry.

  • Non-cleavable three-unit PEG linker suitable for ADC and PROTAC synthesis.
  • Terminal alkyne enables copper-catalyzed azide-alkyne cycloaddition for conjugation to azide-containing molecules.
  • High purity appropriate for research-scale bioconjugation workflows.
  • Available in multiple pack sizes to support small-scale and larger preparative work.
