Used as a highly effective chelating agent in industrial water treatment to prevent scale and corrosion by sequestering metal ions like calcium and iron. Commonly applied in cooling water systems and boiler water treatment due to its stability under high temperature and alkaline conditions. Also utilized in detergents and cleaning formulations to enhance performance by controlling water hardness. Shows good biodegradability resistance, making it suitable for closed-loop systems where long-term stability is required. Frequently chosen in oilfield applications to control scale formation in production equipment.
