I. [Product Description]
Tosyl-PEG-NH2 (Tosyl-Polyethylene Glycol-Amine) is a multifunctional organic intermediate with both high coupling activity and excellent water solubility. It is widely used in the synthesis of pharmaceutical intermediates and the construction of catalyst carriers. The tosyl group (Tosyl) can act as an activating group to participate in nucleophilic substitution reactions, while the amino group (NH2) provides an active site for subsequent functional modification. It is a core raw material for the modification of polymer materials and the design of biocompatible interfaces.
