Diethylenetriaminepentaacetic acid (DTPA)
Technical specifications 6-09-07-1673-88
DTPA is an edetate and a chelating agent used in preparing radiopharmaceuticals. DTPA has a strong affinity for iron and other heavy metals, thereby is used in the treatment of poisoning from heavy and radioactive metals. DTPA may chelate metallic moieties of unbound, extracellular radio-immunotherapeutics, thereby aggregating radioimmunotherapeutics locally to higher concentrations, and improving tumor cell radiocytotoxicity, while sparing normal tissues from the radiocytotoxic effects. It is also used as a color stabilizer for synthetic fiber and as a titrant.
