I. [Product Description]
NHS-PEG-DTPA (N-hydroxysuccinimide ester-polyethylene glycol-diethylenetriaminepentaacetic acid) is a multifunctional organic intermediate, possessing both high catalytic activity and molecular coupling ability. The synergistic effect of the NHS ester group and the DTPA chelating group in its structure endows it with significant value in the fields of biomolecule labeling and metal ion loading. Meanwhile, the polyethylene glycol segment (PEG) confers excellent hydrophilicity and steric hindrance stability, making it an ideal choice for the development of pharmaceutical intermediates and the construction of catalytic systems.
