I. [Product Description] 
TF-PEG-Vitamin D is a functionalized organic intermediate based on the covalent coupling of transferrin and vitamin D through polyethylene glycol (PEG), which combines biocompatibility and molecular programmability. This compound can serve as a highly efficient pharmaceutical intermediate and play a key role in targeted delivery systems and bioconjugation technologies. Its PEG segment provides excellent solvent dispersibility and stability, making it suitable for the construction of complex catalytic systems.
