Usage

General Description

1,2-Benzoquinone dioxime is a chemical compound primarily used as a chelating agent and for the detection of copper ions. It is a colorless, crystalline solid that forms a red complex with copper ions, making it useful for quantifying the amount of copper in a solution. 1,2-Benzoquinone dioxime is also used in some industrial processes as a stabilizer and inhibitor, as well as in the production of certain dyes and pharmaceuticals. However, it is important to handle this compound with caution, as it is toxic and can cause irritation to the skin, eyes, and respiratory system if not handled properly. Overall, 1,2-Benzoquinone dioxime plays a significant role in various industries but should be used and handled with care due to its toxic nature.

Effect of substituents on spin density in benzimidazole nitronyl nitroxide radicals studied by electron spin resonance

Several novel benzimidazole-3-oxide-1-oxyl radicals with substituents at 5 and/or 6 position were synthesized. The ESR analysis of nitrogen hyperfine coupling constants (hfccs) revealed that substituents at 5 and 6-position affect the spin density to greater extent than substituents on the phenyl ring at 2-position. Density functional theory calculations of nitrogen hfccs were performed using several different Pople type basis sets, as well as double and triple zeta quality individual gauge for localized orbital (IGLO-II, IGLO-III) and electron paramagnetic resonance (EPR-II, EPR-II) basis sets. Experimental and theoretical hfccs are compared.
