I. [Product Description] 
PASP-PEG-NH2 is a multifunctional polymer organic intermediate. It combines the excellent biocompatibility of polyaspartic acid (PASP) with the high stability of polyethylene glycol (PEG), and the terminal amino functional group endows it with high-efficiency coupling activity. This compound has important application values in the fields of catalyst carriers, nanomaterial synthesis, and polymer functionalization.
