Used primarily as a biocide in water treatment systems, this compound effectively controls microbial growth in industrial water circuits, including cooling towers and paper mill systems. It disrupts cell metabolism in bacteria and fungi, making it effective against sulfate-reducing bacteria and slime-forming microorganisms. Its stability in aqueous environments allows for sustained activity, especially in systems prone to biofouling. Additionally, it is employed in metalworking fluids to prevent spoilage caused by microbial contamination, extending fluid life and maintaining performance. The compound is often used in combination with other biocides to enhance broad-spectrum efficacy and reduce resistance development.
