용도

p-Toluenesulfonic acid monohydrate is used as a catalyst in the synthesis of resveratrol, in oxane derivatives as an antimalarial agent, as substituted piperidine and unsymmetrical benzyl. It acts as a catalyst in the preparation of 1,3,5-trisubstituted pyrazoles derivatives, selenated ketene dithioacetals, triazoloquinazolinone and benzimidazoquinazolinone derivatives. It also serves as an intermediate in the esterification and in reductive amination reactions.

참고

Hygroscopic. Incompatible with strong oxidizing agents and strong bases.
