Propargyl-PEG8-NH2 is an alkyne-terminated polyethylene glycol (PEG8) amine linker used for bioconjugation and linker synthesis. It provides a terminal alkyne for click chemistry and a primary amine for further derivatization, with a PEG8 spacer to improve solubility and spacing between conjugated moieties.

• Provides a terminal alkyne group for copper-catalyzed azide-alkyne cycloaddition (click chemistry).
• Contains a primary amine for amide formation and further functionalization.
• PEG8 spacer improves solubility and reduces steric hindrance.
• High chemical purity suitable for research applications.
• Colorless to light yellow liquid, convenient for solution-phase coupling reactions.
• Commonly used in PROTAC, ADC, and general bioconjugation workflows.
