I. [Product Description]
FA-PEG-Mal (Maleimide-Polyethylene Glycol-Folic Acid) is a multifunctional organic intermediate that combines a targeting ligand (folic acid) and a thiol-specific reactive group (maleimide). Its core value lies in enhancing water solubility and biocompatibility through the PEG chain, and it is suitable for the preparation of pharmaceutical intermediates, as a catalyst for bioconjugation reactions, and in the synthesis of functionalized materials.
