Carboxy-PEG4-sulfonic acid
PROTAC Linker
Carboxy-PEG4-sulfonic acid is a polyethylene glycol (PEG)-based linker designed for use in the synthesis of PROTACs (proteolysis-targeting chimeras). This compound features a carboxylic acid functional group that enhances solubility and facilitates conjugation, making it ideal for generating bifunctional compounds that promote targeted protein degradation. Its application in PROTAC development enables researchers to explore novel therapeutic strategies by selectively modulating protein levels in cellular environments.
