Bis-propargyl-PEG7 is a homobifunctional reagent with two propargyl groups that can be used to form triazole linkages with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The hydrophilic PEG units help improve the solubility of the molecule in aqueous environment.
Bis-propargyl-PEG6 is a PEG-based PROTAC linker used in the synthesis of PROTACs. Bis-propargyl-PEG6 can be used to synthesize the polymer linked multimers of guanosine-3', 5'-cyclic monophosphates[1]. Bis-propargyl-PEG6 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
