I. [Product Description]
TOS-PEG-COOH is a multifunctional organic intermediate that combines the reactive groups of tosylate with the modifiability of carboxyl groups. It is widely used in the synthesis of polymer materials and bioconjugation reactions. Its PEG segment provides excellent water solubility and biocompatibility, making it an ideal choice for the development of pharmaceutical intermediates and catalyst loading.
