Diethylenetriaminepentaacetic Acid is a component of manganese and zinc fertilizers.Pentetic acid is mainly used as a chelating agent in the preparation of imaging and contrast agents for radionuclide and magnetic resonance imaging.It is also used as a carrier excipient for neutron-capture isotopes in, for example, radiotherapy.Pentetic acid-isotope complexes have also been considered as model active substances in scintigraphic imaging studies.Pentetic acid has been used to chelate metal ions to reduce formation of reactive oxygen species during lyophilization.
Storage
The activity of pentetic acid as a chelating agent may cause unwanted effects in formulations containing metal ions. The desired chelate may be displaced by other ions from the formulation.-20°C
