Used as a corrosion inhibitor in industrial water treatment systems, helping to protect metal surfaces in cooling circuits and heating systems. Commonly applied in metalworking fluids to enhance lubricity and prevent rust formation during machining operations. Functions as an acid gas scrubbing agent in gas treatment processes due to its ability to absorb CO₂ and H₂S. Serves as a building block in the synthesis of surfactants and emulsifiers for agrochemicals and coatings. Also utilized in personal care formulations as a pH adjuster and stabilizer in cosmetics and cleaning products.
