Bis-propargyl-PEG7 is a polyethylene glycol (PEG)-based linker utilized in the synthesis of proteolysis targeting chimeras (PROTACs). It is particularly employed for the synthesis of polymer-linked multimers of guanosine-3',5'-cyclic monophosphates[1].

Bis-propargyl-PEG6 can be utilized to synthesize polymer-linked multimers of guanosine-3', 5'-cyclic monophosphates, serving as reagents for signal transduction research, modulators of cyclic nucleotide-regulated binding proteins and isoenzymes, and ligands for affinity chromatography, antibody production, or diagnostic applications (e.g., on chip surfaces) [1].
