2-Ethylbenzenesulfonyl chloride

Description:
2-Ethylbenzenesulfonyl chloride, with the CAS number 34586-43-1, is an organic sulfonyl chloride characterized by the presence of a sulfonyl group (-SO2Cl) attached to a 2-ethyl-substituted benzene ring. This compound is typically a colorless to pale yellow liquid, known for its strong reactivity due to the sulfonyl chloride functional group, which can readily participate in nucleophilic substitution reactions. It is soluble in organic solvents such as dichloromethane and ether but is generally insoluble in water. 2-Ethylbenzenesulfonyl chloride 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 cause irritation to the skin, eyes, and respiratory system. Proper safety precautions, including the use of personal protective equipment and working in a well-ventilated area or fume hood, are essential when working with this compound.
