Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling water circuits. It helps protect metal surfaces, especially ferrous alloys, from oxidative degradation by forming a protective film. Also employed in some specialized dye formulations due to its conjugated structure, contributing to light absorption properties in the visible range. Shows potential in research settings as a scaffold for developing bioactive compounds, including antimicrobial and antioxidant agents, owing to its ability to chelate metal ions and interact with biological targets.
