mPEG-Chloride is a linear, monofunctional polyethylene glycol (PEG) derivative featuring a reactive chloride (Cl) terminal group. As an efficient leaving group, the chloride enables nucleophilic substitution reactions with primary amines, hydrazides, hydroxyls, or carboxylic acids, making mPEG-Cl a versatile intermediate for PEGylation and custom PEG synthesis. The PEG backbone improves aqueous solubility and biocompatibility, supporting applications in drug delivery, protein and small-molecule modification, and advanced materials research.

​Available in multiple molecular weights with reliable supply from gram to large-scale GMP production, mPEG-Chloride ensures consistency and flexibility for both early-stage research and scale-up needs.
