<p>Deferiprone is a chelating agent with an&nbsp;affinity&nbsp;for ferric ion (iron III). Deferiprone binds with ferric ions to form neutral 3:1 (deferiprone:iron) complexes that are stable over a wide range of pH values. Deferiprone has a lower binding affinity for other metals such as copper, aluminum and&nbsp;zinc&nbsp;than for iron.</p>
