Propargyl-PEG4-NHS ester is a propargyl-terminated polyethylene glycol (PEG4) N-hydroxysuccinimide (NHS) ester used as a linker and click-chemistry reagent for bioconjugation and small-molecule attachment. It combines a reactive NHS ester for amine coupling with an alkyne handle for copper-catalyzed azide-alkyne cycloaddition.

  • Provides an alkyne handle for click chemistry.
  • Contains an NHS ester for efficient amine coupling.
  • Four-unit PEG spacer improves solubility and flexibility.
  • Suitable for linker construction, ADC and PROTAC assembly, and general bioconjugation.
  • Storage: typically kept frozen to preserve reactivity.
