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%

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-(Acetylamino)phenyl benzenesulfonate

Acta Crystallographica Section E Structure Reports Online, 2007
The phenyl and acetyl­amino­phenyl rings of the title compound, C14H13NO4S, are at an angle of 71.57 (5)°, with the acetyl­amino group rotated by 16.3 (1)° from coplanarity with the ring to which it is attached. The structure is stabilized by the presence of N—H⋯O hydrogen bonds which create infinite one-dimensional chains along [010]; weak C—H⋯O inter­

5-Formyl-2-methoxyphenyl benzenesulfonate

Acta Crystallographica Section E Structure Reports Online, 2006
In the title compound, C14H12O5S, the isovanillin group makes a dihedral angle of 37.45 (15)° with the phenyl ring. The crystal packing is stabilized by a weak non-classical inter­molecular C—H⋯O hydrogen bond that links mol­ecules into a chain.
