Application:
Pyridinium p-Toluenesulfonate (CAS: 24057-28-1) is used as an intermediate in the organic synthesis. Used as general industrial fine chemical. Used as organic soluble source of Pyridium ion. It is intermediate of Tacrolimus and Orlistat Immunosuppressant, anti-obesity/pancreatic lipase inhibitor. In organic synthesis, PPTS is used as a weakly acidic catalyst, providing an organic soluble source of pyridinium (C5H5NH+) ions. It is also a commonly used catalyst for the preparation of acetals and ketals from aldehydes and ketones. As a co-catalyst with L-proline improved both yield and enantioselectivity of an asymmetric aldol condensation between dioxanones and aldehydes.
