Used as a biocide in industrial water treatment systems to control microbial growth, particularly in cooling towers and paper mill systems. It effectively targets bacteria, fungi, and algae, helping prevent biofouling and system degradation. Often applied in combination with other antimicrobial agents to enhance efficacy and broaden the spectrum of activity. Its stability in aqueous solutions and fast-acting nature make it suitable for intermittent dosing programs. Also utilized as a preservative in latex emulsions and water-based paints to extend shelf life by inhibiting microbial contamination during storage.
