The Pyridine Sulfur Trioxide Complex is an important reagent for mild sulfonations and sulfations and acts as a reagent for the Parikh-Doering oxidation of alcohols into aldehydes.
As a sulfonation and sulfation reagent PSS is mainly used in the synthesis of complex and sensitive molecules in pharmaceutical and agrochemical applications.
CABB is the leading manufacturer of Pyridine Sulfur Trioxide Complex of high purity. PSS can be regarded the standard reagent with good stability and high reactivity. Further sulfur trioxide amine complexes with different reactivity (like Trimethylamine SO3 or N,N-Dimethylformamide SO3) are available on request.
