I. [Product Description]
This product is a transferrin-polyethylene glycol-sulfadimethoxine conjugate (TF-PEG-sulfadimethoxine), which belongs to high-purity organic intermediates and combines the functions of targeted carriers and active group modification. Its core value lies in the stable modification of biological macromolecules through PEG bridging. It is suitable for the preparation of pharmaceutical intermediates and the immobilization of biocatalysts, with precise molecular weight control and excellent water solubility.
