CAS 4025-75-6

4-Nitrobenzenemethanesulfonyl chloride

Description:

4-Nitrobenzenemethanesulfonyl chloride, with the CAS number 4025-75-6, is an organic compound characterized by the presence of a nitro group and a sulfonyl chloride functional group. It typically appears as a yellow to orange crystalline 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. This compound is often used as a reagent in organic synthesis, particularly in the preparation of sulfonamides and other derivatives. It is important to handle 4-nitrobenzenemethanesulfonyl chloride with care, as it can be corrosive and may pose health hazards if inhaled or if it comes into contact with skin. Proper safety precautions, including the use of personal protective equipment, are essential when working with this substance in a laboratory setting.
