I. [Product Description]
Tosylate-PEG-phosphoric acid is a multifunctional organic intermediate. Through the high reactivity of the tosylate group and the coordination ability of the phosphate group, it enables precise molecular coupling. Its polyethylene glycol (PEG) segment provides excellent water solubility and biocompatibility, and is of great value in catalyst loading, polymer material modification, and functional surface construction.
