I. [Product Description] 
FA-PEG-Polystyrene (Folic Acid-Polyethylene Glycol-Polystyrene) is a functionalized polymer organic intermediate. Through the covalent coupling of the folic acid targeting ligand with the PEG chain, the material is endowed with excellent water solubility and biocompatibility. This compound can be used as a pharmaceutical intermediate for the construction of targeted carriers or as a functional template in catalytic systems to achieve highly selective molecular modification.
