  • Cleavable four-unit PEG linker suitable for bioconjugation.
  • NHS ester functional group for efficient amine coupling.
  • Alkyne handle enables CuAAC (click chemistry) with azides.
  • Typical purity around 95.0% for research use.
  • Molecular weight approximately 653.63 g/mol; viscous light-yellow appearance.
