4-Methoxy-2,5-dimethylbenzenesulfonyl chloride

Description:
4-Methoxy-2,5-dimethylbenzenesulfonyl chloride, with the CAS number 91179-12-3, is an organic compound characterized by the presence of a sulfonyl chloride functional group attached to a substituted aromatic ring. This compound features a methoxy group and two methyl groups on the benzene ring, which contribute to its chemical reactivity and physical properties. It is typically a colorless to pale yellow liquid or solid, depending on its purity and form. The sulfonyl chloride group makes it a potent electrophile, allowing it to participate in various chemical reactions, such as nucleophilic substitutions, where it can react with amines, alcohols, and other nucleophiles to form sulfonamides or sulfonate esters. Due to its reactivity, it is often used as a reagent in organic synthesis and in the preparation of sulfonyl derivatives. However, it is important to handle this compound with care, as sulfonyl chlorides can be corrosive and may release toxic gases upon reaction with water or moisture.
