Used primarily as a chelating agent in water treatment processes to inhibit scale formation and control corrosion in industrial systems. It effectively binds with metal ions like calcium and magnesium, preventing them from depositing on surfaces. In the oil and gas industry, it is employed in well stimulation and acidizing treatments to enhance production by dissolving mineral deposits. Additionally, it finds application in the formulation of cleaning agents for removing hard water stains and rust. Its ability to stabilize metal ions also makes it useful in the textile and paper industries for improving processing efficiency.
