Pyridine sulfur trioxide Usage And Synthesis
  • Chemical Propertieswhite solid
  • UsesPyridine-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.
  • UsesUsually used for sulfations of alcohols, sulfonations, deoxygenations and other reductions, oxidations with DMSO.
  • Purification MethodsWash 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].
