Used primarily as a chelating agent in various industries. In agriculture, it helps in micronutrient fertilizers to improve plant absorption of essential metals. In water treatment, it binds to metal ions to prevent scaling and corrosion in boilers and cooling systems. In the pharmaceutical industry, it stabilizes formulations by sequestering metal impurities. Additionally, it is employed in analytical chemistry as a complexometric titrant for metal ion determination. Its ability to form stable complexes with metal ions makes it valuable in cleaning products to remove metal stains.
