Ionescu, Maria; Panea, Ioan published an article in 1967, the title of the article was Infrared spectra of some sulfamides.Synthetic Route of 97-09-6 And the article contains the following content:
A series of sulfamides were pelletized with KBr (1:300 mg./mg.), and the ir spectra were determined The data were tabulated for the bands corresponding to νs–…C, νs–…N, νs–…O, and The first 3 bands at 1090, 1050, and 1030 cm.-1, resp., are present in the spectra of the arylsulfamides in the 1100-1000-cm.-1 range, in addition to the bands corresponding to the νβ-CH of the substituted benzene nucleus. In many cases, these bands coupled with each other or with addnl. bands. The band at 913 cm.-1 in I was used for quant. anal. The ir spectrum of the equimol. mixture of I and its isomer showed that it was additive, each vibration (even of the same bond but in different connection) manifesting its presence by a corresponding maximum Determinations, by using various amounts of I and II and measuring the extinction by the base line method, verified the rectilinear correlation between extinction and concentration of I, when the latter is >90%, but if it is <60% the error is >>2.8%. 16 references. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Synthetic Route of 97-09-6
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.
