I. [Product Description]
TF-PEG-Chloride is a functionalized organic intermediate formed by the covalent coupling of transferrin and polyethylene glycol (PEG), which combines biocompatibility with chemical modification activity. This compound can be used as an efficient pharmaceutical intermediate for the directional modification of biological macromolecules and the construction of carriers. Its PEG segment provides excellent water solubility and stability, while the chloride group provides active sites for subsequent catalytic reactions or functionalization derivatization.
