N3-PEG4-C2-NHS ester is an azide-terminated polyethylene glycol (PEG4) N-hydroxysuccinimide (NHS) ester used as a bifunctional linker for bioconjugation and click-chemistry applications, including antibody-drug conjugate assembly and labeling of biomolecules.

  • Azide functional group enables copper-catalyzed and strain-promoted click reactions.
  • NHS ester reacts readily with primary amines to form stable amide bonds.
  • Peg4 spacer provides hydrophilicity and conformational flexibility.
  • High purity supports reliable research-grade conjugation.
  • Stability under recommended cold-storage conditions for long-term use.
