Dodecylamine is widely used as a corrosion inhibitor in industrial water treatment processes, particularly in cooling systems and boilers, and in oil and natural gas processing, where it forms a protective layer on metal surfaces to prevent rust, degradation, and scale formation in pipes and equipment. In the mining industry, it serves as a flotation agent to separate valuable minerals from ore by selectively binding to mineral particles and aiding their recovery. It is also employed as an emulsifier and surfactant in the production of cosmetics, detergents, and cleaning products such as shampoos, soaps, and dishwashing liquids, where it helps stabilize mixtures and reduce surface tension. Additionally, dodecylamine is utilized in the synthesis of organic compounds, including pharmaceuticals and agrochemicals, as an intermediate or catalyst in chemical reactions. In agriculture, it is used as an ingredient in pesticides and soil conditioners to enhance nutrient absorption by plants. Its antimicrobial properties make it useful in certain disinfectants and preservatives.
