3-Nitrobenzenesulfonyl Chloride

Description:

3-Nitrobenzenesulfonyl chloride, with the CAS number 121-51-7, is an aromatic sulfonyl chloride that features a nitro group and a sulfonyl chloride functional group attached to a benzene ring. This compound is typically a yellow to brown solid at room temperature and is known for its strong electrophilic properties, making it a useful reagent in organic synthesis. It is highly reactive, particularly towards nucleophiles, and can participate in various chemical reactions, including acylation and sulfonylation. The presence of the nitro group enhances its electrophilicity, facilitating reactions with amines and alcohols to form sulfonamides and sulfonate esters, respectively. 3-Nitrobenzenesulfonyl chloride is also sensitive to moisture and should be handled with care, as it can release toxic gases upon hydrolysis. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound due to its corrosive nature and potential health hazards.
