Mal-PEG4-propargyl is a bifunctional PEG4 linker bearing a maleimide and a propargyl (alkyne) group. It is designed for use in bioconjugation and linker assembly, enabling thiol-maleimide coupling and copper-catalyzed azide-alkyne cycloaddition (CuAAC) to attach diverse ligands or linkers.

  • Maleimide group enables rapid, selective thiol conjugation.
  • Propargyl (alkyne) group supports CuAAC "click" reactions.
  • PEG4 spacer improves solubility and reduces steric hindrance.
  • Low molecular weight (311.33 g·mol⁻¹) for minimal steric impact.
  • High supplied purity (99.7%) for reliable synthetic performance.
