p-Toluenesulfonic acid, also known as tosylate or para-toluene sulfonate, is a member of the class of compounds known as p-methylbenzenesulfonates. p-Methylbenzenesulfonates are benzenesulfonic acids (or derivative thereof) carrying a methyl group at the para- position. p-Toluenesulfonic acid is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). p-Toluenesulfonic acid (PTSA or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH3C6H4SO3H. It is a white solid that is soluble in water, alcohols, and other polar organic solvents. The CH3C6H4SO2– group is known as the tosyl group and is often abbreviated as Ts or Tos. Most often, TsOH refers to the monohydrate, TsOH•H2O. It is a white solid that is soluble in water, alcohols, and other polar organic solvents (Wikipedia).
