APN-C3-PEG4-azide is a PEG-based heterobifunctional linker for PROTAC assembly and bioconjugation. It combines a thiol-reactive 3-arylpropiolonitrile (APN) group with a PEG4 spacer terminating in an azide, enabling selective cysteine modification and subsequent conjugation via copper-catalyzed or strain-promoted azide-alkyne cycloadditions.

  • Thiol-reactive APN moiety enables selective cysteine conjugation.
  • PEG4 spacer provides flexibility and water solubility.
  • Terminal azide enables copper-catalyzed and strain-promoted click reactions.
  • High purity suitable for synthetic and bioconjugation workflows.
  • Available in multiple small-scale quantities for research use.
