I. [Product Introduction]
Mal-PEG-NH2 (Maleimide-Polyethylene Glycol-Amine) is a highly reactive organic intermediate that combines the efficient thiol coupling ability of the maleimide group with the excellent biocompatibility of the PEG segment. It is widely used in biomolecule modification, material surface functionalization, and nano-carrier preparation. Its amine terminal supports further derivatization, making it an ideal pharmaceutical intermediate and catalyst carrier for the development of functional polymer materials.
