Uses Pyridine-Sulfur Trioxide Complex is used in the sulfation of squid ink polysaccharides (SIPs) as a potential candidate compound for the prevention of tumor metastasis. Pyridine-Sulfur Trioxide Complex is also used in the preparation and anticoagulation test of sulfated silk fibroin. Usually used for sulfations of alcohols, sulfonations, deoxygenations and other reductions, oxidations with DMSO. 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.
