Used primarily as a chelating agent in water treatment processes, it effectively binds to metal ions, preventing scale formation and corrosion in industrial systems. It is also applied in the formulation of detergents and cleaning agents, where it enhances the removal of metal stains and improves overall cleaning efficiency. In the field of agriculture, it serves as a soil additive to improve nutrient uptake by plants, particularly phosphorus, promoting healthier crop growth. Additionally, it finds use in the production of flame retardants, contributing to the fire resistance of various materials. Its ability to form stable complexes with metals makes it valuable in certain medical and pharmaceutical applications, such as in the development of targeted drug delivery systems.
