DTPA
Diethylene triaminopentaactetate is a chelating agent that has a very high
affinity for ferric ions. It is listed in the Merck Index as a therapeutic
chelating agent for iron, but doesn't specify whether it is used in treating
anemia or iron overload. Its utility over EDTA seems to be that it binds
ferric ions more tightly than other metal ions. Chemically it is quite
similar to EDTA, so I would expect similar stability with respect to the
light-induced reactions that can reportedly lead to oxidation of the chelating
agent.
