Used as a phase transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases by improving reactant solubility and increasing reaction rates. Commonly applied in the synthesis of fine chemicals, pharmaceuticals, and agrochemicals where efficient mixing of aqueous and organic phases is required.

Also serves as a corrosion inhibitor in industrial formulations due to its ability to form protective films on metal surfaces.

Additionally, employed in the preparation of surfactants and emulsifiers for use in lubricants, coatings, and specialty cleaning products. Its long hydrocarbon chains contribute to strong surface activity and stability in non-polar environments.

Furthermore, used as a surfactant in the separation and extraction of heavy metals such as copper, nickel, and cobalt from solutions, particularly in solvent extraction systems, significantly enhancing metal separation efficiency. Commonly applied in mining and metal recycling industries due to its effectiveness in moderate to strong acidic conditions and stability for repeated use. It also acts as an emulsion stabilizer and dispersant in oil and paint products, preventing particle aggregation and extending product shelf life.
