Pentetic acid or diethylenetriaminepentaacetic acid (DTPA) is an aminopolycarboxylic acid consisting of a diethylenetriamine backbone with five carboxymethyl groups. The molecule can be viewed as an expanded version of EDTA and is used similarly. It is a white solid with limited solubility in water.

Pentetic acid, also known as diethylenetriaminepentaacetic acid (DTPA), is a synthetic polyamino carboxylic acid with eight coordinate bond forming sites that can sequester metal ions and form highly stable DTPA-metal ion complexes. DTPA, along with its calcium and zinc trisodium salts, are the only FDA approved agents for the treatment of ...

2014年2月12日 · Potentiometric titrations have been conducted to determine protonation constants and stability constants for DTPA and corresponding rare earth metal complexes at 2.0 mol·L −1 ionic strength. Ionic strength was adjusted with two different background electrolytes, NaClO 4 and NaSO 3 CF 3.

DTPA is a cell-impermeable metal chelating agent. 1, 2 It chelates copper, iron, zinc, and manganese, as well as calcium, magnesium, and plutonium. 1, 3 DTPA has been used as a metal chelating agent in the study of ferroptosis. 4 It reduces the skeletal plutonium burden and incidence of bone tumors, as well as increases survival in a mouse model...

Studies of the stability of various metal EDTA, DTPA and DOTA complexes in order to evaluate their applicability as non-sorbing tracers have been performed. In laboratory tests, the stability generally increases for the individual metal ions in the EDTA<DTPA<DOTA order.

2013年4月1日 · Electrochemical kinetics of Ce (IV), Cr (III) and V (IV) and their diethylenetriaminepentaacetic acid (DTPA) complexes are studied by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) on Pt-electrode.

DTPA (Diethylenetriaminepentaacetic acid) is a chelating agent commonly used in various industrial and medical applications. Its ability to bind and trap metal ions through a process called chelation makes it a valuable tool in many fields, including medicine, agriculture, and environmental science.
