Maleimide PEG Hydroxyl is a bifunctional polyethylene glycol reagent featuring a maleimide group for thiol conjugation and a terminal hydroxyl group. Synthesized via ring-opening polymerization of ethylene oxide followed by functionalization, it serves as a critical linker in bioconjugation. Typical molecular formula: CnH2n+4OnS (varies by MW); CAS No.: varies by specific chain length.
Store under inert atmosphere at -20°C to prevent hydrolysis. Avoid contact with moisture and strong oxidizers. Not approved for direct human injection without rigorous purification and regulatory clearance.
