I. [Product Description]
Tosyl-PEG-tyrosine is a multifunctional organic intermediate that combines the activation properties of the tosyl group with the excellent water solubility and biocompatibility of polyethylene glycol (PEG). It is suitable for the modification of polymer materials, bioconjugation, and the construction of catalytic systems. The tyrosine residue in its structure provides specific reaction sites, making it of great value in the synthesis of pharmaceutical intermediates and the development of functional carriers.
