4-Methoxy-2-nitrobenzenesulfonyl chloride

Description:
4-Methoxy-2-nitrobenzenesulfonyl chloride, with the CAS number 18092-54-1, is an organic compound characterized by the presence of a sulfonyl chloride functional group attached to a benzene ring that also features a methoxy and a nitro substituent. This compound typically appears as a yellow to orange solid or liquid and is known for its reactivity, particularly due to the sulfonyl chloride group, which can participate in nucleophilic substitution reactions. The methoxy group contributes to the compound's electron-donating properties, while the nitro group is electron-withdrawing, influencing the compound's overall reactivity and stability. It is often used as an intermediate in organic synthesis, particularly in the preparation of sulfonamide derivatives and other functionalized aromatic compounds. Due to its reactive nature, it should be handled with care, as it can be corrosive and may pose health hazards upon exposure. Proper safety measures, including the use of personal protective equipment, are essential when working with this substance.
