Propargyl-PEG2-Tos（Cat No.:I016008） is a PEG-based PROTAC linker utilized in the synthesis of PROTACs (proteolysis-targeting chimeras). It consists of a PEG (polyethylene glycol) chain linked to a tosyl (tosylate) group through a propargyl linker. This linker allows for the conjugation of a target protein-binding ligand to a ligand that recruits an E3 ubiquitin ligase, facilitating targeted protein degradation. Propargyl-PEG2-Tos serves as a crucial component in the construction of PROTAC molecules, enabling the development of novel therapeutics for diseases associated with specific protein targets.
