I. [Product Description]
Tosyl-PEG-DTPA is a multifunctional organic intermediate that combines the high reactivity of the tosyl group with the excellent water solubility of polyethylene glycol (PEG). It is suitable for coupling reactions, polymer carrier construction, and metal chelation catalytic systems. The diethylenetriaminepentaacetic acid (DTPA) group in its structure can efficiently complex metal ions, which is of great value in the synthesis of pharmaceutical intermediates and the design of catalysts.
