A novel colorimetric chemosensor 1 was designed and synthesized for Fe3+/2+ and pyrophosphate. Sensor 1 showed a selective color change toward both Fe3+ and Fe2+ from yellow to brown in a near-perfect aqueous solution The detection limits (0.36 μM and 0.37 μM) for Fe3+ and Fe2+ were much lower than the guideline (5.37 μM) set by the Environmental Protection Agency (EPA) for iron in drinking water. Sensor 1 could be used to quantify Fe3+ in real water samples. Moreover, the resulting Fe3+-2·1 complex can detect pyrophosphate selectively over various anions especially including phosphate-based anions through a metal-complex displacement method. Based on UV-vis titrations, Job plot and ESI-mass spectrometry analyses, the sensing mechanisms of Fe3+, Fe2+ and PPi were proposed. In the experiment, the researchers used many compounds, for example, 3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7Application of 54802-10-7).
3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7) belongs to benzofurans derivatives. Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. As benzofurans are prone to undergo ring opening of the heterocycle, examples of reduction of this type of aromatics by using dissolving metals are rather scarce.Application of 54802-10-7
