PTAD-PEG8-alkyne is a cleavable antibody-drug conjugate (ADC) linker containing an eight-unit polyethylene glycol (PEG8) spacer and a terminal alkyne functional group for click chemistry. It is used as a small-molecule building block in bioconjugation and ADC synthesis, enabling controlled release and modular attachment strategies. Molecular formula: C31H48N4O13; molecular weight: 684.73 g·mol⁻¹.

  • Cleavable linker enables release of payload under defined conditions.
  • PEG8 spacer increases solubility and provides flexibility in conjugates.
  • Terminal alkyne allows copper-catalyzed azide-alkyne cycloaddition (click chemistry).
  • Suitable for use in antibody-drug conjugate synthesis and other bioconjugation workflows.
  • Stable when stored at -20°C in pure form; follow solvent storage recommendations for stability.
