The author of 《Bio-potent sulfonamides》 were Dineshkumar, Selvakumar; Thirunarayanan, Ganesamoorthy. And the article was published in Journal of the Chilean Chemical Society in 2019. Name: 4-Chlorobenzenesulfonyl chloride The author mentioned the following in the article:
Some 4-(substituted phenylsulfonamido)benzoic acids have been synthesized by fly-ash:H3PO3 nano catalyst catalyzed condensation of substituted benzenesulfonyl chlorides and 4-aminobenzoic acid in ultrasound irradiation conditions. The yields of the sulfonamides are more than 90%. The synthesized 4-(substituted phenylsulfonamido) benzoic acid derivatives were characterized by their phys. constants, anal. and spectroscopic data. Antimicrobial activities of all sulfonamides were measured by Bauer-Kirby disk diffusion method. After reading the article, we found that the author used 4-Chlorobenzenesulfonyl chloride(cas: 98-60-2Name: 4-Chlorobenzenesulfonyl chloride)
4-Chlorobenzenesulfonyl chloride(cas: 98-60-2) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Name: 4-Chlorobenzenesulfonyl chloride
