Boc-NH-PEG4 is a Boc-protected polyethylene glycol (PEG4) linker used as a spacer in PROTAC, ADC, and other bioconjugation syntheses. It provides a four-unit PEG spacer with a Boc-protected amino terminus that enables orthogonal deprotection and downstream functionalization. The material is supplied as a colorless to light yellow liquid and is suitable as a building block in small-molecule conjugates.

  • Four-unit PEG spacer for controlled linker length.
  • Boc-protected amino terminus enables orthogonal deprotection and diversification.
  • High purity suitable for synthetic applications (about 99.5%).
  • Liquid form simplifies handling and dosing.
  • Recommended storage at -20°C to preserve stability.
