I. [Product Description]
FA-PEG-Tosylate is a bifunctional organic intermediate. Through the precise coupling of folic acid (FA), polyethylene glycol (PEG), and tosylate, it combines the characteristics of targeted modification and active group activation. This compound can be used as an efficient catalyst or linker arm and is widely applied in the fields of bioconjugation, nanocarrier preparation, and polymer material synthesis. The customizable PEG chain length endows the product with excellent solubility and spatial hindrance control ability.
