I. [Product Description]
Mal-PEG-COOH (Maleimide-polyethylene glycol-carboxylic acid) is a bifunctional PEG derivative that combines the high reactivity of the maleimide group with the coupling ability of the carboxyl group. It is widely used in the preparation of organic intermediates, the modification of pharmaceutical intermediates, and the design of bioconjugation catalysts. Its PEG chain can effectively improve water solubility and reduce immunogenicity, making it suitable for site-specific coupling reactions in complex systems.
