Used primarily as a corrosion inhibitor in industrial water treatment systems, especially in cooling water circuits. It is effective in preventing metal degradation by forming a protective film on metal surfaces, particularly copper and its alloys. The compound is valued for its stability under varying pH conditions and its ability to work synergistically with other inhibitors and biocides. It is also applied in oilfield systems to protect downhole equipment from corrosion caused by sour environments (H₂S and CO₂). Its imidazole-based structure enhances surface adsorption, making it suitable for long-term protection in recirculating systems.
