Gue, Anne-Marie; Lattes, Armand; Laurent, Elisabeth; Mauzac, Monique; Mingotaud, Anne-Francoise published the artcile< Characterization of recognition sites for diethyl 4-nitrobenzylphosphonate, an organophosphate pesticide analogue>, SDS of cas: 112-63-0, the main research area is diethyl nitrobenzylphosphonate complexing fluoroalc aromatic acid recognition site.
In a first step towards developing chem. sensors using mol. imprinted materials, the complexing characteristics of di-Et 4-nitrobenzylphosphonate, an organophosphate pesticide analog, have been studied. Two mols. have been assessed as potential interacting moieties, specifically 1,1,1-trifluoro-2-(trifluoromethyl)pent-4-en-2-ol and 4-(3-butenyloxy)benzoic acid. The interactions have been first characterized by regular methods, such as 1H, 31P NMR and IR spectroscopy. These showed a stoichiometry 1/1 for both complexes and association constants 40 ± 10 and 12 ± 2 M-1, resp. In a second step, isothermal titration calorimetry was used and a method was developed to obtain low-association constants The association constant for the fluoroalc. ligand was 63 ± 0.7 M-1. For the benzoic acid derivative, an appropriate model could not be found, preventing the evaluation of this constant
Analytica Chimica Acta published new progress about Sensors. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, SDS of cas: 112-63-0.
