Description and applications
Pyridine sulfur trioxide complex is a mild, stable, and controllable sulfating and sulfonating reagent with the chemical formula C5H5NO3S. Chemical Properties
- Appearance: White to cream, pale yellow, or beige powder/crystal.
- CAS Number: 26412-87-3
- Nature: Adduct formed from the Lewis base pyridine and the Lewis acid sulfur trioxide.
- Solubility: Dissolves well in polar organic solvents.
- Stability: Moisture-sensitive, but much more stable and manageable than free sulfur trioxide.
Applications
- Chemical
- Laboratory
- Sulfonation
