Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling water and boiler systems, where it forms a protective film on metal surfaces to prevent oxidation and degradation. Also employed as a biocide or antimicrobial agent due to its ability to disrupt microbial cell membranes, making it effective in controlling slime and bacterial growth in paper mills and oilfield operations. Acts as a flotation agent in mineral processing for the separation of specific ores. Additionally, serves as a surfactant and emulsifier in specialty formulations where high hydrophobicity and stability are required. Its long alkyl chains provide strong surface activity, useful in the formulation of coatings, lubricants, and antistatic agents. Furthermore, it is used as an intermediate in the synthesis of quaternary ammonium compounds, which exhibit bactericidal and virucidal properties.
