2-Chloro-3-methylbenzenesulfonyl chloride

Description:
2-Chloro-3-methylbenzenesulfonyl chloride, with the CAS number 1191545-47-7, is an organic compound characterized by the presence of a sulfonyl chloride functional group attached to a chlorinated aromatic ring. This compound features a methyl group and a chlorine atom positioned on the benzene ring, which influences its reactivity and solubility. It is typically a colorless to pale yellow liquid or solid, depending on the temperature and purity. The sulfonyl chloride group makes it a potent electrophile, allowing it to participate in various chemical reactions, such as nucleophilic substitutions and acylation reactions. It is often used as a reagent in organic synthesis, particularly in the preparation of sulfonamides and other sulfonyl derivatives. Due to its reactive nature, it should be handled with care, as it can be corrosive and may release toxic gases upon contact with water or moisture. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound.
