《””Turn-on”” fluorescent biosensors for high selective and sensitive detection of Al3+ ion》 was written by Wang, Pengfei; Liu, Lijie; Meng, Fanda; Khan, Maroof Ahmad; Li, Hui. Recommanded Product: 673-22-3 And the article was included in Frontiers in Chemistry (Lausanne, Switzerland) in 2020. The article conveys some information:
A series of new compounds (1-4) based on pyrrole hydrazone Schiff bases were designed and synthesized. The interactions of these new compounds with metal ions and their fluorescent recognition were investigated. All compounds showed “”turn-on”” fluorescence in the presence of Al3+ in aqueous solution Their sensing behaviors with Al3+ were studied using photophys. experiments, ESI-MS spectrometry anal., 1H NMR titration, and DFT calculation The detection limits of 1-4 for the anal. of Al3+ were found to reach a 10-8 M level in aqueous solution, which are far lower than the WHO guidelines for drinking water (7.41 mM for Al3+). A high selectivity test paper has been fabricated for Al3+ detection based on sensor 3. Theor. calculations (DFT) have been carried out to elucidate the configuration of 1-4 and their Al complexes and rationalize exptl. absorption data. In the experiment, the researchers used 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Recommanded Product: 673-22-3)
2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3) is employed in the synthesis of Schiff base ligand. It is applied as a reactant in the synthesis of LPA1R antagonists used in the inhibition of LPA-induced proliferation and contraction of normal human lung fibroblasts. Also used in the synthesis of tyrosine kinase 6 proteinase inhibitors.Recommanded Product: 673-22-3
