Used as a key raw material in the production of linear alkylbenzene sulfonate (LAS), a widely used surfactant in household and industrial detergents. Its strong acidic nature makes it effective in emulsifying oils and removing dirt, especially in laundry detergents, dishwashing liquids, and hard surface cleaners. Also employed as an acid catalyst in organic synthesis and in emulsion polymerization processes, such as the production of synthetic rubbers and resins. Due to its solubilizing and wetting properties, it finds use in agricultural formulations, textile processing, and enhanced oil recovery methods.
