Azido-PEG2-C2-acid is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.
Azido-PEG2-C2-sulfonic acid is a polyethylene glycol (PEG) derived linker compound employed for the synthesis of proteolysis-targeting chimeras (PROTACs) [1].
