I. [Product Description]
Tosylate-PEG-DTPA is a multifunctional organic intermediate that combines the high reactivity of tosylate with the biocompatibility of the PEG chain. It is suitable for the synthesis of pharmaceutical intermediates and the construction of catalyst carriers. The DTPA group in its core structure provides strong metal ion chelating ability and can be widely used in the field of functional material modification.
