Used as a biocide in industrial water systems to control microbial growth, particularly in cooling towers and paper mill systems. Effective against a broad spectrum of bacteria and fungi due to its membrane-disrupting properties. Also employed as a preservative in latex emulsions and water-based paints to prevent spoilage. Shows potential in antifouling coatings for marine applications by inhibiting biofilm formation. Its long alkyl chain enhances lipid solubility, improving penetration into microbial cell membranes.
