Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811034234
Abstract: In the title compound, C19H15O2P, the dihedral angles between the benzoic acid ring and the phenyl rings are 75.64 (7) and 80.88 (7)°; the dihedral angle between the phenyl rings is 81.35 (7)°. In the crystal, inversion dimers linked by pairs of O—H...O hydrogen bonds generate R22(8) loops between the head-to-head carboxylic acid groups.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808016942
Abstract: The title compound, C17H16O5, is an important intermediate for the synthesis of side-chain ligands for polymeric liquid crystals. The propoxy and benzoic acid groups subtend dihedral angles of 4.36 (6) and 55.35 (6)°, respectively, with the central benzoyloxy unit. The crystal structure is stabilized by an intermolecular O—H...O hydrogen bond.

Abstract: The title compound, C16H13ClO3, is an important intermediate in the conversion of isocoumarin to 3,4-dihydroisocoumarin. The two aromatic rings are oriented at a dihedral angle of 67.18 (3)°. In the crystal structure, intermolecular O—H...O hydrogen bonds link the molecules into centrosymmetric dimers. There is also a C—H...π contact between the benzoic acid and 4-chlorobenzyl rings.
Potentiometric Responses of Ion-Selective Electrodes Doped with Diureidocalix[4]arene towards Un-dissociated Benzoic Acid  [PDF]

Sensors , 2007, DOI: 10.3390/s7081655
Abstract: Diureidocalix[4]arene have been applied as new ionophore in liquid membraneelectrode (ISE) sensitive towards un-dissociated benzoic acid. The electrode demonstratedresponse towards benzoic acid with the detection limit 2.0 x 10-4 M which is sufficient forthe determination of benzoic acid added to beverages as preservative in milimolarconcentration. The selectivity coefficients measured by the matched potential method(MPM) showed its good selectivity against common anions present in drink samples. Allmeasurements were made in presence of 1.0 x 10-2 M NaHSO4 pH 3.0 in order to reducethe influence of OH-. The applicability of diureidocalix[4]arene incorporated ISE has beenchecked by recovery test of benzoic acid in the presence of artificial drink matrix and bystandard addition method.
4-(Diphenylphosphinoyl)benzoic acid  [cached]

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808031449
Abstract: Molecules of the title compound, C19H15O3P, are connected by O—H...O hydrogen bonds between the carboxylic acid OH group and the phosphinoyl O atom, forming chains running along the crystallographic b axis.
4-(Cyclopropanecarboxamido)benzoic acid  [cached]
Zhong-Qiang Sun,Zhen-Ya Ding,Zhi-Yu Shao
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812038196
Abstract: In the title compound, C11H11NO3, the dihedral angle between the benzene ring and the cyclopropane ring is 63.2 (1)°. In the crystal, molecules are linked through classical cyclic carboxylic acid O—H...O hydrogen-bond interactions [graph set R22(8)] giving centrosymmetric dimers which are extended along the b-axis direction through amide N—H...O hydrogen-bond interactions, giving one-dimensional ribbon structures. Weak C—H...O interactions are also present in the structure.
Antifungal Activity of Salicylanilides and Their Esters with 4-(Trifluoromethyl)benzoic Acid  [PDF]
Martin Krátky,Jarmila Vin?ová
Molecules , 2012, DOI: 10.3390/molecules17089426
Abstract: Searching for novel antimicrobial agents still represents a current topic in medicinal chemistry. In this study, the synthesis and analytical data of eighteen salicylanilide esters with 4-(trifluoromethyl)benzoic acid are presented. They were assayed in vitro as potential antimycotic agents against eight fungal strains, along with their parent salicylanilides. The antifungal activity of the presented derivatives was not uniform and moulds showed a higher susceptibility with minimum inhibitory concentrations (MIC) 3 0.49 μmol/L than yeasts (MIC 3 1.95 μmol/L). However, it was not possible to evaluate a range of 4-(trifluoromethyl)benzoates due to their low solubility. In general, the most active salicylanilide was N-(4-bromophenyl)-4-chloro-2-hydroxybenzamide and among esters, the corresponding 2-(4-bromophenylcarbamoyl)-5-chlorophenyl 4-(trifluoromethyl) benzoate exhibited the lowest MIC of 0.49 μmol/L. However, the esterification of salicylanilides by 4-(trifluoromethyl)benzoic acid did not result unequivocally in a higher antifungal potency.

3-{[4-(4-Pyridyl)pyrimidin-2-yl]sulfanylmethyl}benzoic acid  [cached]
Hai-Bin Zhu,Hai Wang,Jun-Feng Ji
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808036799
Abstract: The title compound, C17H13N3O2S, was prepared by reaction of 4-(4-pyridyl)pyrimidine-2-thiol with 3-(bromomethyl)benzoic acid under basic conditions. Each pair of molecules is mutually linked via O—H...N hydrogen bonds, forming a dimer. The packing of the dimers is stablized by C—H...π interactions involving the methylene unit of the –CH2S– linkage and benzene rings.

Abstract: The asymmetric unit of the title compound, C8H6N4O2·H2O, consists of one 4-(1H-tetrazol-5-yl)benzoic acid molecule and one water molecule. Hydrogen-bonding and π–π stacking (centroid–centroid distance between tetrazole and benzene rings = 3.78 ) interactions link the molecules into a three-dimensional network.
