I. [Product Description] 
FA-PEG-Lysines (Folic acid-Polyethylene glycol-Lysine) is a high-performance organic intermediate. Through the precise coupling of folic acid with the polyethylene glycol-modified lysine structure, it combines both targeting ability and biocompatibility. This compound can be used as a pharmaceutical intermediate or a catalyst carrier material, and is widely applied in the fields of bioconjugation, nanomaterial synthesis, and functional modification.
