I. [Product Description]
COOH-PEG-Poly-Arginines is a multifunctional amphiphilic organic intermediate. It is formed by the covalent bonding of carboxyl-modified polyethylene glycol and polyarginine, combining the biocompatibility of PEG and the high-efficiency loading capacity of polyarginine. This compound can be used as a pharmaceutical intermediate for complex molecular assembly or as a carrier in catalytic systems to improve reaction efficiency. Its modular structure supports customized functional expansion.
