I. [Product Description] 
This compound is a multifunctional conjugate constructed from the liver cancer-specific targeting peptide SP94 (SFSHHTPILPLC), polyethylene glycol (PEG), and functionalized methotrexate (MTX) units. As a high-purity organic intermediate, it can be applied in the development of targeted carrier systems. Its core value lies in the enhanced water solubility and molecular customizability provided by the PEG segment, making it suitable for the synthesis of pharmaceutical intermediates and the construction of catalytic systems.
