Used as a corrosion inhibitor in industrial applications, particularly in oil and gas pipelines, to protect metal surfaces from degradation caused by harsh environments. It is also employed in the formulation of biocides, helping to control microbial growth in water treatment systems and industrial processes. Additionally, it serves as a phase transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases. Its properties make it suitable for use in coatings and paints, enhancing durability and resistance to environmental factors.
