description Product Description
This compound is a specialized intermediate in organic synthesis, featuring a phenyl-terminated polyethylene glycol (PEG) chain with a tosylate leaving group at the other end. It is primarily used for PEGylation reactions, where the tosylate is displaced by nucleophiles to attach PEG chains to molecules, enhancing solubility, stability, and bioavailability in pharmaceutical applications. This makes it valuable in drug development for modifying proteins, peptides, and small molecules. Additionally, it serves as a building block in polymer chemistry for creating functionalized materials with improved properties, such as in advanced drug delivery systems and biomaterials.
