Fmoc-PEG4-NHS ester is a heterobifunctional PEG-based linker that contains an Fmoc-protected amine and an N-hydroxysuccinimide (NHS) activated ester. It is used to introduce a PEG4 spacer and an activated ester for amine coupling in peptide conjugation, PROTAC synthesis, and other bioconjugation workflows.

  • Heterobifunctional linker with Fmoc-protected amine and NHS ester.
  • Peg4 spacer improves solubility and increases linker flexibility.
  • Activated NHS ester enables rapid coupling to primary amines.
  • Suitable for peptide conjugation and targeted degrader (PROTAC) synthesis.
  • High reported purity supports use in research-grade synthesis.
