Used primarily as a corrosion inhibitor in concrete and steel structures, it protects reinforcing bars from rusting, especially in harsh environments like coastal areas or where de-icing salts are applied. It is also employed in cooling systems and as a heat transfer fluid additive to prevent metal degradation. In the construction industry, it enhances the durability of concrete by reducing the risk of freeze-thaw damage. Additionally, it serves as a stabilizer in certain industrial processes and acts as a precursor in the synthesis of other chemicals.
