Pyridine sulfur trioxide Chemical Properties,Uses,Production

Chemical Properties

white solid

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.

Uses

Usually used for sulfations of alcohols, sulfonations, deoxygenations and other reductions, oxidations with DMSO.

Purification Methods

Wash the solid with a little CCl4, then H2O to remove traces of pyridine sulfate, and dry it over P2O5. [Baumgarten Chem Ber 59 1166 1926, Olah et al. Synthesis 59 1979, Beilstein 20/5 V 184].
