5-Chloro-2-methylbenzenesulfonyl chloride

Description:
5-Chloro-2-methylbenzenesulfonyl chloride, with the CAS number 34981-38-9, 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 due to the sulfonyl chloride group, which can participate in nucleophilic substitution reactions, making it useful in the synthesis of various organic compounds, including pharmaceuticals and agrochemicals. The presence of the chlorine atom and the methyl group on the benzene ring influences its electronic properties and steric hindrance, affecting its reactivity and interactions with other chemical species. As with many sulfonyl chlorides, 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, are essential when working with this substance.
