It enables efficient biotinylation and affinity tagging of azide-containing molecules for pull-downs, imaging, or PROTAC assembly, offering good solubility and high chemical purity for biochemical applications.

  • Terminal alkyne for CuAAC click chemistry.
  • PEG4 spacer to improve solubility and reduce steric hindrance.
  • Biotin handle for strong streptavidin/avidin affinity capture.
  • High purity suitable for analytical and preparative workflows.
  • Suitable for bioconjugation, labeling, and PROTAC linker assembly.
