1-(4-Aminobenzyl)-DTPA（Cat No.:M113882）, short for diethylenetriamine pentaacetic acid, is a chelating agent modified by an aminobenzyl group. It forms strong complexes with metal ions, notably those used in medical imaging. This compound includes a phenyl ring linked to a backbone of nitrogen and oxygen atoms from the DTPA structure, enhancing its solubility and binding properties. It is commonly employed in radiopharmaceutical applications to safely transport radioactive isotopes within the body, allowing for precise diagnostic imaging, such as in MRI scans or cancer detection, thanks to its ability to complex with gadolinium and other metals.
