Used primarily as a chelating agent for the treatment of iron overload, especially in patients with thalassemia or other chronic anemias who receive frequent blood transfusions. It binds excess iron in the body, forming a stable complex that is then excreted in urine, helping to prevent organ damage caused by iron accumulation. Also used in cases of acute iron poisoning and aluminum overload in patients on dialysis. Has been explored for its potential in treating neurodegenerative diseases involving metal ion imbalance and in enhancing MRI contrast by modulating metal ion distribution. Additionally, it is employed in research to study oxidative stress, as it can suppress iron-mediated free radical formation.
