用途有機合成原料。
説明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.
使用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.
純化方法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].
