Used as a corrosion inhibitor in industrial cooling systems and metalworking fluids. It effectively protects copper and its alloys from degradation by forming a protective film on the metal surface. Also applied in water treatment processes to prevent metal corrosion in pipelines and heat exchangers. Shows good stability under high temperature and wide pH range, making it suitable for harsh environments. Additionally, it has potential as a ligand in coordination chemistry for metal ion extraction and sensing applications.
