In forensic ballistics, gunshot residue (GSR) particles can be detected using screening or presumptive tests which are mainly focused on the chromophoric reaction. Most serve as an initial indication for a investigator at crime scene before instrumental analysis definitive identification. The methods known to convenient, have fast analysis, and minimal preparation. GSR well-known method of dete...

Abstract The introduction of a -NO 2 substituent in o -aminophenol would create an open-unit polymer suitable for different applications. We report the synthesis poly(5-nitro-2-aminophenol) by aniline-catalyzed oxidative polymerization. structure was intensively characterized spectroscopic techniques, elemental analysis, cyclic voltammetry, electrical conductivity and microscopic measurements s...

A novel metal complexes Cu (II), Co Cd Ru (III) from azo ligand 5-((2-(1H-indol-2-yl) ethyl) diazinyl)-2-aminophenol were synthesized by simple substitution of tryptamine with 2-aminophenol. Structures all the newly compounds characterized FT IR, UV-Vis, Mass spectroscopyand elemental analysis. In addition measurements magnetic moments, molar conductance and atomic absorption. Then study their ...

Two new phenylpropanoid glycosides named cuneataside E (1) and cuneataside F (2), were isolated from the aerial parts of Lespedeza cuneata (Dum. Cours.) G. Don, whose structures were E and Z isomer, respectively. Their structures were elucidated on the basis of comprehensive spectroscopic analysis (UV, IR, HR-ESI-MS, 1D and 2D NMR). In in vitro bioassays at 10 μmol/L, compound 1 showed moderate...

2-p-substituted phenyl-2-benzimidazolo acetonitriles (1a-5a) were prepared by the reaction of benzimidazole , p-substituted benzaldehydes and Sodium cyanide. A series of 2-(α-p -Substituted phenyl-αbenzimidazolo) methyl benzoxazoles (1b-5b) were synthesized by the reaction of 2-p-substituted phenyl-2benzimidazolo acetonitrile(1a-5a) and o-aminophenol in presence of Conc. HCl. These compounds we...

Acetaminophen, p-aminophenol, and oxyphenbutazone interfere with the glucose oxidase/peroxidase method for glucose. Structurally related compounds that lack a free phenolic hydroxyl group (acetanilide, aniline, and phenylbutazone) do not interfere. During the analytical procedure acetaminophen is consumed. One mole of acetaminophen leads to an apparent loss of four moles of glucose. The hexokin...

Oxidation of formaldehyde (HCHO) is very important, owing to its use in fuel cells. Modification of electrodes surfaces is an excellent way to decrease the overpotentials as well as to increase the current density of the voltammetric response.pt as most efficient metal catalyst can easily be poisoned by product of oxidation and also it has high cost. In this work an efficient and low cost elect...

Despite the known side effects of liver damage, among other issues, paracetamol (N-acetyl-p-aminophenol) continues to be one of the most commonly used drugs worldwide for conditions such as pain and fever and it is often purchased without medical prescription. It is usually administered as a tablet, but it is also available as solutions, suppositories and intravenous preparations. In addition, ...
