I. [Product Description] 
TF-PEG-Azithromycin is a high-purity organic intermediate. It achieves directional modification through the covalent coupling of transferrin and polyethylene glycol (PEG). It can be used as a pharmaceutical intermediate or a catalyst for bioconjugation reactions. The unique hydrophilic PEG chain binds to the targeting ligand, significantly enhancing the stability and solubility of the molecule, and is suitable for the construction of complex synthesis systems.
