Used primarily as a chelating agent in water treatment processes to control scale formation and inhibit corrosion in industrial systems. It is effective in sequestering metal ions such as calcium, magnesium, and iron, making it valuable in boiler water treatment and cooling systems. Additionally, it is employed in the textile industry as a dyeing auxiliary to improve color fastness and uniformity. Its ability to form stable complexes with metal ions also finds applications in detergents and cleaning formulations, enhancing their efficiency in hard water conditions. In agriculture, it is utilized as a micronutrient carrier in fertilizers to improve nutrient uptake by plants.
