I. [Product Description]
DTPA-PEG-valine (Diethylenetriaminepentaacetic acid-Polyethylene glycol-Valine) is a high-performance organic intermediate with both chelation coordination and biocompatible properties. Its pentadentate ligand structure can serve as a catalyst support, and the PEG segment endows it with the ability to regulate water solubility. It is widely used in the synthesis of pharmaceutical intermediates and the modification of functional materials.
