Sodium p-toluenesulfonate is an organic compound with the formula CH3C6H4SO3Na. It is white, water-soluble solid. It is produced by the neutralization toluenesulfonic acid with sodium hydroxide. It is also a common product from the reactions of sodium-based reagents with toluenesulfonates.[1]

Heating this salt in strong base results in desulfonation, giving, after acid workup, p-cresol.[2]
