I. [Product Description]
Tosylate-PEG-ASP is a multifunctional organic intermediate. Through the efficient coupling of the tosylate active group with the polyethylene glycol (PEG) chain and aspartic acid (ASP), it is suitable for site-directed modification in the synthesis of complex molecules. Its unique bifunctional structure can be used as a pharmaceutical intermediate or a catalyst carrier, and it performs excellently in the development of biocompatible materials and functionalized reaction systems.
