I. [Product Description]
DTPA-PEG-Tosyl (Diethylenetriaminepentaacetic acid-Polyethylene glycol-Tosylate) is a multifunctional organic intermediate with both chelating coordination and efficient coupling properties. The DTPA group in its structure can act as a metal ion chelating agent, the PEG segment provides excellent water solubility and biocompatibility, and the tosylate group provides active sites for subsequent reactions. It is widely used in catalyst design, functionalization of polymer materials, and synthesis of pharmaceutical intermediates.
