I. [Product Introduction]
Tosylate-PEG-VA (Tosylate-Polyethylene Glycol-Valeric Acid) is a multifunctional organic intermediate with excellent chemical modifiability and biocompatibility. Its tosylate group can serve as a highly efficient leaving group and is widely used in coupling reactions and polymer synthesis. The PEG segment endows the molecule with water solubility and low immunogenicity, making it suitable for the development of pharmaceutical intermediates and the construction of catalyst carriers.
