I. [Product Description]
TF-PEG-COOH, Transferrin-Polyethylene Glycol-Carboxyl, is a multifunctional organic intermediate. Through the precise coupling of transferrin with terminal carboxyl-functionalized PEG, it combines biocompatibility and chemical modification activity. This compound can be used as a pharmaceutical intermediate for targeted carrier construction or as an amphiphilic linking bridging molecule in catalytic systems, significantly enhancing the stability and functional tunability of composite materials.
