2-CHLOROSULFONYL-PYRIDINIUM, CHLORIDE

Description:
2-Chlorosulfonyl-pyridinium chloride is a chemical compound characterized by its pyridinium structure, which includes a pyridine ring substituted with a chlorosulfonyl group. This compound typically appears as a white to off-white solid and is known for its hygroscopic nature, meaning it can absorb moisture from the air. It is soluble in polar solvents, such as water and alcohols, due to the presence of the pyridinium cation. The chlorosulfonyl group imparts significant reactivity, making this compound useful in various chemical synthesis applications, particularly in the formation of sulfonamides and other sulfonyl-containing compounds. Additionally, it can act as a chlorinating agent, facilitating the introduction of chlorine into organic molecules. Safety precautions are essential when handling this compound, as it may be corrosive and can cause irritation to the skin, eyes, and respiratory system. Proper storage in a cool, dry place away from incompatible substances is recommended to maintain its stability and reactivity.
