In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. 31181-90-5, formula is C6H4BrNO, Name is 5-Bromopicolinaldehyde. For this reason, pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Application of C6H4BrNO.
So, Haeri;Lee, Minji;Kim, Cheal research published 《 A Unique Thiosemicarbazide-Based Colorimetric Chemosensor for Fe2+ in Pure Aqueous Solution with the Lowest Detection Limit》, the research content is summarized as follows. A unique colorimetric chemosensor Hy-bp based on thiosemicarbazide was prepared Hy-bp showed an obvious red-shifted spectrum and unique color change from colorless to deep green only for Fe2+. Detection limit for Fe2+ was 0.34 μM, which is the lowest among those of colorimetric chemosensors previously reported for Fe2+ in pure aqueous solution Hy-bp can be utilized in paper strips and water samples as a colorimetric sensor for detecting Fe2+. The sensing mechanism of Hy-bp for Fe2+ was demonstrated by UV-vis spectroscopy, Job plot, FT-IR and 1H NMR titrations
