4-Ethoxy-Benzenesulfonyl Chloride

Description:
4-Ethoxy-benzenesulfonyl chloride, with the CAS number 1132-17-8, is an organic compound characterized by the presence of a sulfonyl chloride functional group attached to a benzene ring that also bears an ethoxy substituent. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its purity and temperature. It is known for its reactivity, particularly in nucleophilic substitution reactions, where the sulfonyl chloride group can act as a leaving group. The ethoxy group enhances its solubility in organic solvents, making it useful in various synthetic applications, including the preparation of sulfonamides and other sulfonyl derivatives. 4-Ethoxy-benzenesulfonyl chloride is sensitive to moisture and should be handled with care, as it can hydrolyze to form the corresponding sulfonic acid and hydrochloric acid. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound due to its corrosive nature and potential health hazards.
