MPEG20K Succinimidyl Carboxymethyl Ester is a Y-shaped PEGylation reagent designed for bioconjugation. Its core process involves activating carboxyl groups with NHS esters to react with primary amines. The molecular formula is typically C106H211NO47 (approximate). CAS No: 198538-89-5.
Store at -20°C under inert atmosphere. Avoid moisture to prevent hydrolysis of the NHS ester. Handle with standard PPE; not for direct clinical injection without formulation.
