Used primarily as a corrosion inhibitor in industrial applications, especially in cooling systems and antifreeze formulations. It protects copper and its alloys from degradation by forming a protective film on metal surfaces. Also functions as an additive in lubricants and metalworking fluids to enhance performance and extend equipment life. Shows effectiveness in mixed-metal environments, making it suitable for use in automotive and HVAC systems. Additionally, it is employed in some water treatment processes to maintain system integrity and prevent metal ion leaching.
