Merian, Ernest published an article in 1960, the title of the article was Differentiation between alkyl aryl sulfone groups and aromatic sulfonamide groups by use of infrared spectrography.COA of Formula: C6H5ClN2O4S And the article contains the following content:
Application of infrared absorption bands to differentiate between alkyl aryl sulfone groups and primary, secondary, and tertiary aromatic sulfonamide groups was discussed. Infrared absorption spectra of the following compounds were charted: methanesulfonyl chloride; 4-methylsulfonyl-1-chloro-2-nitrobenzene; 4-methylsulfonyl-1-amino-2-chlorobenzene; a monoazo dye formed of 6-methylsulfonyl-2-diazobenzothiazole and N-ethyl-N-cyanoethyl-m-toluidine; 1-chloro-2 nitrobenzene-4-sulfonamide; 1-chloro-2-nitrobenzene-4-sulfonmethylamide; 1-chloro-2-nitrobenzene-4-sulfonethylamide; 1-amino-2-chlorobenzene-4-sulfonmethylamide; dimethylaminosulfonyl chloride; 1-chloro-2-nitrobenzene-4-sulfondiethylamide; 1-amino-2-chlorobenzene-4-sulfondimethylamide; and 1-aminobenzene-4-sulfondimethylamide. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).COA of Formula: C6H5ClN2O4S
3-Nitro-4-chlorobenzenesulfonamide(cas:97-09-6) belongs to amides. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis.
