2-Methyl-4-nitrobenzenesulfonyl chloride

Description:

2-Methyl-4-nitrobenzenesulfonyl chloride, with the CAS number 21320-90-1, is an organic compound characterized by the presence of a sulfonyl chloride functional group attached to a benzene ring that also features a methyl and a nitro substituent. This compound typically appears as a yellow to orange solid and is known for its reactivity, particularly due to the sulfonyl chloride group, which can undergo nucleophilic substitution reactions. It is soluble in organic solvents such as dichloromethane and chloroform but is generally insoluble in water. The presence of the nitro group contributes to its electron-withdrawing properties, influencing its reactivity and making it useful in various synthetic applications, including the preparation of sulfonamides and other derivatives. 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 alcohols. Proper safety precautions, including the use of personal protective equipment, are essential when working with this substance.
