In the title compound, C(15)H(18)N(2)O(4), the aromatic rings on the azomethine double bond are trans to each other [C-C=N-C torsion angle = -178.29 (12)°] and they are approximately coplanar, the dihedral angle between them being 5.0 (1)°.

The title compound, C(15)H(20)BrN(3)O(2)S, crystallizes in the thio-amide form and adopts an E,E conformation with respect to the azomethine and hydrazinic bonds, respectively. The mol-ecules are paired through N-H⋯O and O-H⋯S hydrogen bonds, leading to the formation of centrosymmetric dimers in the crystal. These dimers are stacked along the a axis and are inter-connected through N-H⋯S hydroge...

At the concentrations usually employed as a Ca2+ indicator, arsenazo III undergoes a one-electron reduction by rat liver microsomes to produce an azo anion radical as demonstrated by electron spin resonance spectroscopy. Either NADH or NADPH can serve as a source of reducing equivalents for the production of this free radical by rat liver microsomes. The steady state concentration of the azo an...

Benzidine (Bz) is a known human carcinogen. Several azo dyes have been synthesized with Bz. Bz can be metabolically released from azo dyes. In a group of Indian workers producing Bz and azo dyes the presence of hemoglobin (Hb) adducts was investigated. The following Hb adducts were identified and quantified by GC-MS: Bz, N-acetylbenzidine (AcBz), 4-aminobiphenyl (4ABP), aniline. 4ABP and anilin...

We report an indium tin oxide (ITO) free inverted organic solar cell with alternate aluminium doped zinc (AZO) front cathode layer based on the consideration of blocking harmful ultraviolet (UV) rays, which is one prominent reasons for degradation cells. To further enhance power conversion efficiency AZO/ZnO/PTB7:PC71BM/MoO3/Ag cell, plasmonic gold nanoflowers were embedded inside active layer....

An azo dye used as photosensitizers in Dye-sensitized solar cells DSSCs. Azo dyes economically superior to organometallic dyes because they are color variation and cheap. The spectrophotometric evaluation of an azo dye in solution and on a TiO2 substrate show that the dye form J-aggregation on the nanostructured TiO2 substrate. Oxidation potential measurements for used azo dyes ensured an energ...

Fungicides pose a risk for crustacean leaf shredders serving as key-stone species litter breakdown in detritus-based stream ecosystems. However, little is known about the impact of strobilurin fungicides on shredders, even though they are presumed to be most hazardous fungicide class aquafauna. Therefore, we assessed azoxystrobin (AZO) survival, energy processing (leaf consumption and feces pro...

In the presented study, CuO-CoO-MnO/SiO2 nanocomposite was synthesis by Cu(II), Co(II), Mn(II), with 1:1:1 mole ratio and Tetraethyl orthosilicate. azo–azomethine 1-(3-imino-4-hydroxophenylazo-4-nitrobenzene)-4-methyl phenol (L) was synthesized and used as a ligand for capturing the metal ions. Also, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide was applied as the i...

A direct and facile synthesis of highly functional 5-aza-spiro[2,4]heptanes, a valuable structural motif for drug discovery, is developed via catalytic asymmetric 1,3-dipolar cycloaddition of cyclopropylidene acetate and azomethine ylides for the first time.

Generation of azomethine imine and its scope in regioselective 1,3-dipolar cycloaddition (DC) of imine with PhIO toward highly substituted Delta(2)-1,2,4-triazoline, 1,2,4-triazole, and their fused, chiral, and sugar-based analogues are demonstrated.
