COA of Formula: C5H7BrO3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Ethyl 3-bromo-2-oxopropanoate, is researched, Molecular C5H7BrO3, CAS is 70-23-5, about A selective “”turn-on”” sensor for recognizing In3+ and Zn2+ in respective systems based on imidazo[2,1-b]thiazole. Author is Xu, Yuankang; Zhao, Songfang; Zhang, Yanxia; Wang, Hanyu; Yang, Xiaofeng; Pei, Meishan; Zhang, Guangyou.
A new simple and easily synthesized multitarget sensor, (E)-N′-(4-(diethylamino)-2-hydroxybenzylidene)imidazo[2,1-b]thiazole-6-carbohydrazide (X), was designed and synthesized using imidazo[2,1-b]thiazole-6-carboxylic acid and 4-(diethylamino)-2-hydroxybenzaldehyde. X could be used as a sensor to detect In3+ in DMF-H2O buffer solution and detect Zn2+ in EtOH-H2O buffer solution through fluorescence enhancement with detection limits of 1.02 × 10-9 M and 5.5 × 10-9 M, resp. X exhibited an efficient “”off-on-off”” fluorescence behavior by cyclic addition of metal ions (In3+ and Zn2+) and EDTA. The stoichiometry between X and metal ions (In3+ and Zn2+) was 1 : 1. The binding mode and sensing mechanism of X with metal ions (In3+ and Zn2+) was verified by theor. calculations using Gaussian 09 based on B3LYP/6-31G(d) and B3LYP/LANL2DZ basis, resp. Moreover, X could be applied as a potential sensor for the quant. detection of In3+ and Zn2+ with a satisfactory recovery and relative standard deviation (RSD) in real water samples.
