I. [Product Description]
TF-PEG-Estrogen is an organic intermediate based on the covalent coupling of transferrin and estrogen via polyethylene glycol (PEG). It can be used as a highly efficient biocompatible carrier in the development of targeted delivery systems. This compound significantly enhances water solubility and stability through precise PEG modification technology, and is suitable for the preparation of pharmaceutical intermediates requiring precise control of molecular size and the construction of catalytic reaction systems.
