BCN-PEG3-biotin is a click-chemistry linker containing a bicyclononyne (BCN) group, a three-unit polyethylene glycol spacer, and a terminal biotin. It is used for strain-promoted alkyne-azide cycloaddition (SPAAC) with azide-containing molecules and as a biotin tag for affinity capture or detection.

  • Facilitates copper-free SPAAC click reactions.
  • Three-unit PEG spacer improves solubility and reduces steric hindrance.
  • Terminal biotin enables streptavidin-based capture and detection.
  • Supplied as an off-white to light yellow solid with ≥95.0% purity.
  • Soluble in DMSO (100 mg/mL); powder storage recommended at -20°C.
