Description:
4-Chloro-2-methylbenzenesulfonyl chloride, with the CAS number 56157-92-7, is an organic compound characterized by the presence of a sulfonyl chloride functional group attached to a chlorinated aromatic ring. 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 presence of the chloro and methyl substituents on the benzene ring influences its chemical behavior, making it a useful intermediate in organic synthesis, particularly in the preparation of sulfonamides and other sulfonyl derivatives. Additionally, it is important to handle this compound with care, as it can be corrosive and may release toxic gases upon reaction with water or moisture. Proper safety precautions, including the use of personal protective equipment and working in a well-ventilated area, are essential when working with this substance.
