N-(4-Fluorobenzoyl)-2-hydroxy-4-methyl­benzohydrazide

In the title compound, C(15)H(13)FN(2)O(3), the aromatic rings are aligned at an angle of 10.15 (3)°. The mol-ecules are packed with π-π stacking inter-actions [mean inter-planar distances of 3.339 (2) and 3.357 (3) Å] and the crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds. An intramolecular N-H⋯O interaction also occurs.

Antioxidant Activity of 3-[N-(Acylhydrazono)ethyl]-4-hydroxy-coumarins.

A series of 3-acylhydrazono-4-hydroxycoumarins were synthesized via condensation of 3-acetyl-4-hydroxycoumarin with appropriate hydrazides. The structures of the newly-synthesized compounds were characterized by spectral and elememental analysis or HRMS measurements. Their antioxidant properties were evaluated by using scavenging effects on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical as well a...

Urinary 4-hydroxy-3-methoxymandelic (vanillylmandelic) acid, 4-hydroxy-3-methoxyphenylacetic (homovanillic) acid, and 5-hydroxy-3-indoleacetic acid determined by liquid chromatography with electrochemical detection.

We describe a simple liquid-chromatographic assay of urinary 4-hydroxy-3-methoxymandelic (vanillylmandelic) acid, 4-hydroxy-3-methoxyphenylacetic (homovanillic) acid, and 5-hydroxy-3-indoleacetic acid with electrochemical detection, with direct injection of the sample. The first two analytes are measured simultaneously; 5-hydroxy-3-indoleacetic acid is measured separately. Chromatographic condi...

Synthesis and Characterization of Some Lanthanide(III) Chloro Complexes Derived from 4[N-(4’-Hydroxy-3’-Methoxybenzalidene) Amino] Antipyrine Semicarbazone and 4[N-(3’,4’,5’-Trimethoxybenzalidene) Amino]Antipyrine Semicarbazone

Lanthanide(III) chloro complexes of 4[N-(4’-hydroxy-3’-methoxybenzalidene) amino] antipyrine semicarbazone (HMBAAPS) (I) and 4[N-(3’,4’,5’-trimethoxybenzalidene) amino] antipyrine semicarbazone (TMBAAPS) (II) with the general composition LnCl3.2L (Ln = La, Pr, Nd, Sm, Gd, Tb, Dy or Ho; L = HMBAAPS or TMBAAPS) are reported. All the complexes were synthesized in ethanolic medium and refluxed the ...

Simultaneous liquid-chromatographic analysis for 4-hydroxy-3-methoxymandelic acid and 4-hydroxy-3-methoxyphenylacetic acid in urine.

We describe a rapid, reliable "high-performance" liquid-chromatographic method of simultaneously analyzing for 4-hydroxy-3-methoxymandelic acid (I) and 4-hydroxy-3-methoxyphenylacetic acid (II) in urine. Paired-ion chromatography and amperometric detection are used in the method. A 5-mL aliquot of urine is adjusted to pH 6.1 and subjected to anion-exchange chromatography (Dowex AG 1-X4, 1.8 X 0...
