Used as a biocide in industrial water treatment systems to control microbial growth, particularly in cooling towers and paper mill systems. Effective against bacteria, algae, and fungi due to its ability to release chlorine gradually. Its stability in high-temperature and high-pH environments makes it suitable for harsh industrial conditions. Also employed in oilfield water systems to prevent biofouling and souring caused by sulfate-reducing bacteria. Shows good solubility in organic solvents, allowing for easy formulation in commercial antimicrobial products.
