Used primarily as a corrosion inhibitor in industrial water treatment systems, especially in cooling water and boiler systems. It forms a protective film on metal surfaces, preventing oxidation and degradation caused by water and oxygen exposure. Also employed as an additive in lubricants and cutting fluids to enhance metal protection under high-temperature and high-pressure conditions. Shows biocidal activity, making it useful in controlling microbial growth in aqueous environments. Applied in the formulation of agrochemicals and pharmaceuticals as an intermediate due to its stable heterocyclic structure. Its long alkyl chain contributes to good solubility in nonpolar matrices and enhances surface activity.
