Hirose, Kazuo et al. published their research in Ann. Proc. Gifu Coll. Pharm. in 1955 | CAS: 1146-43-6

N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide (cas: 1146-43-6) belongs to amides. Compared to amines, amides are very weak bases and do not have clearly defined acid–base properties in water. On the other hand, amides are much stronger bases than esters, aldehydes, and ketones. Amides can be freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.HPLC of Formula: 1146-43-6

Antibacterial action of quinone derivatives was written by Hirose, Kazuo;Kitamura, Jiro;Ose, Yoki;Mishima, Toshie. And the article was included in Ann. Proc. Gifu Coll. Pharm. in 1955.HPLC of Formula: 1146-43-6 This article mentions the following:

Fourteen derivatives of R’O2SN:C.CH:CR.C(:O).CH:CH (I) and 1,2,4-HO(R)(R’O2SNH)C6H3 were synthesized and their antibacterial properties were tested. Following compounds were comparatively effective for Staphylococcus pyogenes var. aureus and S. albus, R, R’ given: H, Ph; H, 4-MeC6H4; H, 3-NO2C6H4; and H, 3,4-Ac(HO)C6H3 of the I type. In the experiment, the researchers used many compounds, for example, N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide (cas: 1146-43-6HPLC of Formula: 1146-43-6).
