Oxidation-reduction potentials of N-(arenesulfonyl)quinonimine-arenesulfonamidophenol systems was written by Dubina, V. L.;Burmistrov, K. S.. And the article was included in Zhurnal Organicheskoi Khimii in 1977.Name: N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide This article mentions the following:
Oxidation-reduction potentials (EN) were determined for 11 N-(4-hydroxyphenyl)arenesulfonamides, 3 N-(4-hydroxy-1-naphthyl)benzenesulfonamides, and 5 N-(2-hydroxyphenyl)benzenesulfonamides in a (AcO)4Pb system. Residual (AcO)4Pb was titrated with 0.5M AcONa in glacial AcOH. The highest EN, 0.887 v for N-(4-chloro-2-hydroxyphenyl)benzenesulfonamide, was only 0.014 v higher than the EN for its 5-chloro isomer. In the experiment, the researchers used many compounds, for example, N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide (cas: 1146-43-6Name: N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide).
N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide (cas: 1146-43-6) belongs to amides. In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. As a result of interactions such as these, the water solubility of amides is greater than that of corresponding hydrocarbons. These hydrogen bonds are also have an important role in the secondary structure of proteins.Name: N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide
