Piridiniy p-Toluensulfonat (CAS: 24057-28-1) organik sintezda oraliq mahsulot sifatida ishlatiladi.Umumiy sanoat nozik kimyoviy sifatida ishlatiladi.Piridium ionining organik eruvchan manbai sifatida ishlatiladi.Bu Takrolimus va Orlistat immunosupressantining oraliq mahsuloti, semizlikka qarshi / oshqozon osti bezi lipaz inhibitori.Organik sintezda PPTS zaif kislotali katalizator sifatida ishlatiladi, piridiniy (C5H5NH +) ionlarining organik eruvchan manbasini ta'minlaydi.Shuningdek, u aldegidlar va ketonlardan atsetal va ketallarni tayyorlash uchun keng tarqalgan katalizator hisoblanadi.L-prolin bilan birgalikda katalizator sifatida dioksanonlar va aldegidlar orasidagi assimetrik aldol kondensatsiyasining rentabelligi va enantioselektivligi yaxshilandi.
