Used as a key component in cleaning formulations, particularly for removing mineral deposits and scale from metal and ceramic surfaces. Effective in industrial and household descaling agents due to its ability to chelate metal ions and dissolve rust and lime scale. Also employed in water treatment processes to control pH and inhibit corrosion in cooling systems. Serves as an intermediate in the synthesis of dyes, herbicides, and other sulfonate-based chemicals. Its low volatility and good solubility make it suitable for use in aqueous systems where stability and performance are required over a range of temperatures.
