3,4-Dichlorobenzenesulfonyl chloride

Description:

3,4-Dichlorobenzenesulfonyl chloride, with the CAS number 98-31-7, is an organic compound characterized by its sulfonyl chloride functional group attached to a dichlorobenzene ring. This compound typically appears as a colorless to pale yellow solid and is known for its strong electrophilic properties, making it a useful reagent in organic synthesis, particularly in the formation of sulfonamides and other sulfonyl derivatives. It is moderately soluble in organic solvents such as dichloromethane and chloroform but is generally insoluble in water. The presence of chlorine atoms enhances its reactivity, allowing it to participate in various chemical reactions, including nucleophilic substitutions. However, it is important to handle this compound with care, as it can be corrosive and may 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, are essential when working with this substance.
