Used primarily as a chelating agent, it effectively binds to metal ions, making it valuable in various industrial and laboratory processes. In water treatment, it helps control metal ion concentrations, preventing scale formation and improving system efficiency. In analytical chemistry, it is employed to sequester interfering metal ions, ensuring accurate results in complexometric titrations. Additionally, it finds use in the formulation of cleaning agents, where it aids in removing metal deposits from surfaces. Its ability to stabilize metal ions also makes it useful in certain pharmaceutical and cosmetic applications, where it helps maintain product integrity and performance.
