Used as a biocide in industrial water treatment systems to control microbial growth, particularly in cooling towers and paper mill systems. It disrupts cell membranes in bacteria and fungi, preventing biofilm formation and system fouling. Also employed as a preservative in latex emulsions and water-based paints to extend shelf life. Shows activity against sulfate-reducing bacteria, making it useful in oilfield applications to prevent microbial-induced corrosion. Its lipophilic nature enhances penetration into microbial cells, increasing efficacy at low concentrations.
