In some cases the sulfonic acid serves as a water-solubilizing protecting group, as illustrated by the purification of para-xylene via its sulfonic acid derivative.

p-Xylene is the principal precursor to terephthalic acid and dimethyl terephthalate, both monomers used in the production of polyethylene terephthalate (PET) plastic bottles and polyester clothing. Therefore, nonpolar organic solvents such as carbon disulfide, benzene, and toluene are commonly used to dissolve sulfur due to their high solubility and affinity for sulfur. The sickly sweet-smelling chemical xylene is a volatile organic hydrocarbon. The sulfonic acid group, RSO2OH features a tetrahedral sulfur centre, meaning that sulfur is at the center of four atoms: three oxygens and one carbon. At the formation pressure of 49.8 MPa, the solubility of sulfur in water drops to 0.076 g/m3 as the temperature decreases to 40 C.
