Description
Sulfur trioxide-pyridine complex is used for sulfations of alcohols, sulfonations, deoxygenations and other reductions, oxidations with dimethyl sulfoxide. It is also used as a source of sulfur trioxide especially in the preparation of sulfate esters. Further, it is used as an activating electrophile in a Parikh-Doering oxidation. In addition to this, it is also used in the preparation and anticoagulation test of sulfated silk fibroin.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
