Used extensively in medical and laboratory settings as an anticoagulant for blood samples, preventing clotting by chelating calcium ions. It is a key component in EDTA tubes for hematology tests. In molecular biology, it aids in DNA and RNA isolation by inhibiting nucleases that degrade nucleic acids. Additionally, it is employed in industrial processes to sequester metal ions, preventing scale formation and improving the efficiency of cleaning agents. In agriculture, it helps in micronutrient delivery by stabilizing metal ions in fertilizers. Its chelating properties also make it useful in water treatment to remove heavy metals and in food preservation to maintain color and stability.
