2,4-Dichloro-5-methylbenzenesulfonyl chloride

Description:
2,4-Dichloro-5-methylbenzenesulfonyl chloride, with the CAS number 28286-86-4, is an organic compound characterized by its sulfonyl chloride functional group attached to a chlorinated aromatic ring. This compound typically appears as a white to light yellow solid and is known for its reactivity, particularly in nucleophilic substitution reactions due to the presence of the sulfonyl chloride group. It is soluble in organic solvents such as dichloromethane and chloroform but is generally insoluble in water. The presence of chlorine atoms on the benzene ring enhances its electrophilic character, making it useful in various synthetic applications, including the preparation of sulfonamides and other sulfonyl derivatives. However, it is important to handle this compound with care, as it can be corrosive and may pose health hazards upon exposure. Proper safety measures, including the use of personal protective equipment and working in a well-ventilated area, are essential when working with this chemical.
