TL;DR: In this article, the chemical nature of hydrazones and their biological activities were discussed and the total established conditions for the determination of various metal ions with hydrazone were given.
Abstract: Hydrazones are very important group of analytical regents for the determination of various metal ions by using various analytical techniques. Besides this use of hydrazones are also having biological activities also. In this paper we first discussed about the chemical nature of hydrazones and their biological activities. We mainly focused on the papers which were published during 1980-2011 on analytical applications (spectrophotometric and spectrofluorimetric) of hydrazones. We gave the total established conditions for the determination of various metal ions with hydrazones.

TL;DR: Hydrazones prepared and structurally characterized exhibited fluorescence "turn on" response toward Al3+ in dimethyl formamide/water (DMF/H2O) mixture and showed high selectivity towardsAl3+ over the other common metal ions.

TL;DR: In this article, the structure and properties of bidentate hydrazone ligands were confirmed by spectral and single crystal X-ray diffraction studies, and they showed significant binding towards calf thymus DNA (CT-DNA) via groove binding mode with binding constants in the magnitude 10 4 −10 5 ǫ −1.

TL;DR: Pyridine-2-carbaldehyde 2-hydroxybenzoylhydrazone reacts with iron(II) to produce a green 2:1 complex (λmax. = 640 nm, Iµ= 3.64 × 103 l mol-1 cm-1 in aqueous ethanolic solution, and λmax.
Abstract: Pyridine-2-carbaldehyde 2-hydroxybenzoylhydrazone reacts with iron(II) to produce a green 2:1 complex (λmax. = 620 nm, Iµ= 3.64 × 103 l mol–1 cm–1 in aqueous ethanolic solution, and λmax. = 640 nm, Iµ= 3.67 × 103 l mol–1 cm–1 in chloroform). The green complex, extracted into chloroform, has been used for the spectrophotometric determination of trace amounts of iron. The method has a high selectivity and has been applied to the determination of iron in different samples, such as industrial waste water, non-ferrous materials and minerals.
