Used as a surfactant and biocide in industrial water treatment systems, particularly effective in controlling microbial growth in cooling towers and paper mill systems. Its antimicrobial properties make it suitable for use in disinfectants and sanitizers. Also functions as a phase transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases. Commonly employed in the formulation of fabric softeners due to its ability to bind to textile fibers and impart softness. Additionally, serves as an intermediate in the production of quaternary ammonium compounds used in personal care products and agrochemicals.
