p-Toluenesulfonic acid monohydrate, an oxonium salt, is an inexpensive and easy to handle org-anic catalyst used in org-anic synthesis. The study of its crystalline structure shows that it is monoclinic with P21/c space group. Its solubility in aqueous sulfuric acid solutions has been studied.

Application

p-Toluenesulfonic acid monohydrate (p-TsOH·H2O) may be used as a catalyst in the synthesis of the following:
Unsymmetrical benzils.
Highly substituted piperidines.
1,3,5-Trisubstituted benzenes by trimerization of alkynes.
Triazolo Quinazolinone and benz imidazo quinazolinone derivatives.
1,3,5-Trisubstituted pyrazoles derivatives.
Selenated ketene dithioacetals.
