Antimycobacterial Activity of Salicylanilide Benzenesulfonates [PDF]

Molecules, 2012
A series of eighteen novel esters of salicylanilides with benzenesulfonic acid were designed, synthesized and characterized by IR, 1H-NMR and 13C-NMR. They were evaluated in vitro as potential antimycobacterial agents towards Mycobacterium tuberculosis ...

Diisopropylammonium benzenesulfonate [PDF]

IUCrData, 2018
In the anion of the title molecular salt, C6H16N+·C6H5O3S−, the O atoms of the sulfonate group is rotationally disordered over two sets of sites in a a 0.711 (9):0.289 (9) ratio. The extended structure displays N—H...O hydrogen bonds between the cation and anion, which results in infinite chains propagating parallel to [010].

Photolysis of Benzenesulfonic Acid [PDF]

Bulletin of the Chemical Society of Japan, 1977
Abstract Photolysis of benzenesulfonic acid(1) in an aqueous solution gave sulfurous acid, SO2, and/or sulfuric acid as inorganic products in a total yield of 38.6% based on the consumed 1 along with organic products. The organic products are mainly acidic tarry material containing sulfur(8.7%) together with a small amount of biphenyl (1%

Photolysis of Methyl Benzenesulfonate in Methanol [PDF]

Bulletin of the Chemical Society of Japan, 1975
Abstract The irradiation of methyl benzenesulfonate (1) in methanol undergoes a photolysis (Φdisapp=0.07±0.005) leading to benzene (5–34%), biphenyl (9–15%), and anisole (trace), in place of a photo-addition of methanol to give bicyclohexene derivatives. The rate of desulfonation of 1 is only slightly affected by triethylamine.

Simultaneous Determination of 15 Sulfonate Ester Impurities in Phentolamine Mesylate, Amlodipine Besylate, and Tosufloxacin Tosylate by LC-APCI-MS/MS

Journal of Analytical Methods in Chemistry, 2019
Sulfonate esters have been recognized as potential genotoxic impurities (PGIs) in pharmaceuticals. An LC-MS/MS method was developed and validated for the simultaneous determination of 15 sulfonate esters, including methyl, ethyl, propyl, isopropyl, and n-

4-Nitrophenyl benzenesulfonate

Acta Crystallographica Section E Structure Reports Online, 2007
In the structure of the title compound, C12H9NO5S, the phenyl and 4-nitro­phenyl rings are not coplanar, the dihedral angle being 53.91 (4)°. The structure contains weak inter­molecular C—H⋯O hydrogen bonds and face-to-face π–π inter­actions between symmetry-related phenyl rings (separation 3.664 A).
