4-Chloro-3-nitrobenzenesulfonyl chloride

Description:
4-Chloro-3-nitrobenzenesulfonyl chloride, with the CAS number 97-08-5, is an organic compound characterized by its sulfonyl chloride functional group, which is known for its reactivity in various chemical reactions. This compound features a benzene ring substituted with a chlorine atom at the para position and a nitro group at the meta position relative to the sulfonyl chloride group. It is typically a solid at room temperature and is soluble in organic solvents such as dichloromethane and acetone. The presence of both the nitro and chloro substituents contributes to its electrophilic nature, making it useful in synthetic organic chemistry, particularly in the preparation of sulfonamide derivatives and other functionalized aromatic compounds. Due to its reactive sulfonyl chloride group, it can participate in nucleophilic substitution reactions, often serving as an important intermediate in the synthesis of pharmaceuticals and agrochemicals. Proper handling and storage are essential, as it can be corrosive and may release toxic gases upon hydrolysis.
