Widely used in medicine to treat heavy metal poisoning, particularly lead toxicity, by binding to metal ions and facilitating their excretion through urine. Also employed in blood collection tubes as an anticoagulant, preventing clotting by sequestering calcium ions. In the food industry, acts as a preservative by deactivating metal-dependent enzymes that promote spoilage, helping to maintain color, flavor, and shelf life. Commonly used in cosmetics and personal care products to improve stability by preventing metal-catalyzed degradation. In industrial applications, used in detergents and cleaning agents to soften water by chelating calcium and magnesium ions, enhancing cleaning efficiency. Frequently applied in agriculture to correct micronutrient deficiencies, especially iron, in plants by keeping metal nutrients soluble and available for uptake. Also utilized in laboratory settings to control metal ion activity in biochemical and molecular biology experiments.
