Used as a surfactant and biocide in industrial water treatment systems, helping to control microbial growth and prevent biofouling in cooling towers and paper mill systems. Also serves as an intermediate in the synthesis of quaternary ammonium compounds, which are widely used for their antimicrobial properties in disinfectants and fabric softeners. Its long alkyl chain contributes to membrane disruption in microorganisms, enhancing its effectiveness in antimicrobial formulations. Additionally, it finds use in corrosion inhibition and as a flotation agent in mineral processing due to its surface-active properties.
