N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide (cas: 1146-43-6) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Quality Control of N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide

Imino exchange reaction in a dearomatization strategy: synthesis of N-acyl diarylamines and phenothiazines from two anilines was written by Zhang, Li;Wang, Huiqing;Yang, Bo;Fan, Renhua. And the article was included in Organic Chemistry Frontiers in 2014.Quality Control of N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide This article mentions the following:

N-Sulfonyl cyclohexadienimines generated from an iodine(III)-induced oxidative dearomatization of N-sulfonyl protected para-substituted anilines are ready to undergo an imino exchange reaction with another aniline, which provides an alternative way to access N-acyl diarylamines and phenothiazines. In the experiment, the researchers used many compounds, for example, N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide (cas: 1146-43-6Quality Control of N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide).
