Used as a biocide in industrial water treatment systems to control microbial growth, particularly in cooling towers and paper mill systems. Effective against bacteria, fungi, and algae due to its ability to disrupt cellular metabolism. Also employed as a preservative in latex emulsions and adhesives to prevent spoilage during storage. Its solubility in water and stability over a wide pH range make it suitable for continuous or intermittent dosing in various aqueous environments.
