CAS 98-74-8: Benzenesulfonyl chloride, 4-nitro-

Description: 4-Nitrobenzenesulfonyl chloride, with the CAS number 98-74-8, is an aromatic sulfonyl chloride characterized by the presence of a nitro group attached to a benzene ring that is also bonded to a sulfonyl chloride functional group. This compound typically appears as a yellow to brown solid and is known for its reactivity, particularly in nucleophilic substitution reactions. The sulfonyl chloride group makes it a potent electrophile, allowing it to react with various nucleophiles, including amines and alcohols, to form sulfonamides and sulfonate esters, respectively. It is soluble in organic solvents such as dichloromethane and ether but is generally insoluble in water. Due to its reactive nature, 4-nitrobenzenesulfonyl chloride is often used in organic synthesis, particularly in the preparation of sulfonamide derivatives and other functionalized compounds. However, it should be handled with care, as it can be corrosive and poses health hazards upon exposure. Proper safety precautions, including the use of personal protective equipment, are essential when working with this chemical.
