Hydroxy-PEG3-MS（Cat No.:I044728）is a heterobifunctional polyethylene glycol (PEG) linker consisting of a terminal hydroxyl group and a methanesulfonyl (mesyl, MS) group separated by a PEG3 (triethylene glycol) spacer. The hydroxyl group can participate in further chemical modifications or conjugation reactions, while the mesyl group is a highly reactive leaving group suitable for nucleophilic substitution with thiols, amines, or alkoxides. The PEG3 chain enhances solubility, flexibility, and biocompatibility. Hydroxy-PEG3-MS is commonly used in bioconjugation, surface modification, and the synthesis of functional materials for drug delivery, diagnostics, and polymer engineering applications.
