Cas no 2905-27-3 (3,5-Dimethylbenzenesulfonyl Chloride)
3,5-Dimethylbenzenesulfonyl chloride is a sulfonylation reagent commonly used in organic synthesis, particularly for introducing the 3,5-dimethylbenzenesulfonyl (Mesitylenesulfonyl) group into target molecules. Its key advantages include high reactivity with nucleophiles such as amines and alcohols, facilitating the preparation of sulfonamides and sulfonate esters. The steric hindrance from the two methyl groups enhances selectivity in certain reactions. The compound is stable under typical storage conditions and exhibits good solubility in organic solvents like dichloromethane and THF, making it practical for laboratory use. It is widely employed in pharmaceutical and agrochemical research for intermediate functionalization. Proper handling is required due to its moisture sensitivity and potential corrosiveness.
