Differential pulse voltammetry for determination of benorilate in pharmaceutical formulations at carbon paste electrode was written by Wang, Chengyin;Hu, Xiaoya;Chen, Qian;Rong, Guo. And the article was included in Analytical Letters in 2005.SDS of cas: 5003-48-5 The following contents are mentioned in the article:
Benorilate was determined by the differential pulse voltammetry (DPV) using a carbon paste electrode in 1.25 × 10-3 mol L-1 KH2PO4 and Na2HPO4 buffer solution (pH = 6.88, 25°). The anodic peak potential was +1.020 V (vs. SCE). A good linear relationship was realized between the anodic peak currents and benorilate concentrations in the range of 2.0 × 10-7 to 4.5 × 10-4 mol L-1 with the detection limit of 5.0 × 10-8 mol L-1. The recovery was 94.3 to 104.6% with the RSD of 3.5% (n = 9). The pharmaceutical preparations, benorilate tablets samples, were determined with desirable results. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5SDS of cas: 5003-48-5).
4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.SDS of cas: 5003-48-5
