Photometric characteristics of de-sulfonated pyrocatechol violet and its application to the photometric determination of trace amounts of mercury was written by Chen, Zhaoguo;Chen, Xi. And the article was included in Lihua Jianyan, Huaxue Fence in 2001.Computed Properties of C17H30BrN This article mentions the following:
A method for the spectrophotometric determination of Hg was presented with de-sulfonated pyrocatechol violet (DSPV). In a slightly acidic medium of pH 4.5-6.5, a stable quaternary chelate was formed by DSPV, Hg(II), KBr and DPB. The absorption maximum of the chelate was at 586 nm, the apparent molar absorptivity 9.5 × 105, the detection limit 0.8 ng mL-1, and Beer’s law obeyed at 0.02-4.00 μg/25 mL. The interference of Cd2+ and Pb2+ can be masked by thiolactic acid, and that of Sn2+ eliminated by H2O2. The results obtained by this method agreed very well with those obtained by AAS method. The method was used in the determination of trace Hg in environmental water samples and foodstuff with the relative standard deviation 9.5-13.9% and the recovery 93-116%. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Computed Properties of C17H30BrN).
1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Computed Properties of C17H30BrN
