I. [Product Description]
DTPA-PEG-Lysines is a multifunctional organic intermediate that integrates the strong chelating properties of DTPA, the biocompatibility of PEG chains, and the molecular modification sites of lysine. It is suitable for metal ion loading, polymer material modification, and catalytic system construction. Its modular design allows for precise regulation of the molecular weight and the ratio of functional groups, and it has significant application value in the synthesis of pharmaceutical intermediates and the preparation of nanomaterials.
