Chloro-PEG4-alcohol represents a PEG linker containing a chloride group and a terminal hydroxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The chloride (Cl) is a good leaving group for nucleophilic substitution reactions. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.
