Used as a biocide in industrial water treatment systems to control microbial growth, particularly in paper mills and cooling towers. It prevents slime formation and microbial degradation of materials by targeting bacteria and fungi. Also applied as a preservative in water-based paints and adhesives to extend shelf life. Its effectiveness at low concentrations makes it suitable for continuous dosing in closed-loop systems. Shows activity against sulfate-reducing bacteria, helping prevent corrosion in metal systems.
