Anwendungen & Verwendung
Beschreibung
Pyridine sulphur trioxide is an important reaction reagent that can react with various compounds such as aldehydes, anthracenes and pyrroles to produce other heterocyclic compounds. Pyridine sulphur trioxide is primarily used in addition reactions or sulphonation processes.
Verwenden
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.
