Bis-propargyl-PEG4 is a PEG-based bifunctional linker featuring terminal propargyl (alkyne) groups, designed for conjugation chemistry and PROTAC construction. It provides a short, flexible spacer for joining two ligands via click chemistry.
- Bifunctional PEG4 linker with terminal alkyne groups.
- Enables copper-catalyzed azide-alkyne cycloaddition (click chemistry).
- Useful for PROTAC synthesis and dimer formation.
- Low molecular weight (270.32 g/mol) for compact linker design.
- Stable under recommended storage conditions when kept dry and refrigerated.
