General Description

Diazobenzenesulfonic acid, also known as benzenediazosulfonic acid, is an organic compound commonly used as a reagent in organic synthesis. It is also employed in the preparation of azo dyes and pigments. diazobenzenesulfonic acid is characterized by the presence of two nitrogen and a sulfur atom bonded to a benzene ring, forming a diazonium salt with a sulfonic acid group. The exact properties of diazobenzenesulfonic acid can vary depending on the specific type of diazobenzenesulfonic acid being analyzed, which can be defined by the presence and positioning of various substituents on the benzene ring. It is considered hazardous due to its acute toxicity when ingested, inhaled, or comes into contact with the skin.

A low ion-transfer resistance and high volumetric supercapacitor using hydrophilic surface modified carbon electrodes

A hydrophilic surface modified carbon electrode shows a good electrolyte affinity with homogeneous dispersibility in water, resulting in low ion-transfer resistance and a uniform and dense electrode to give a high volumetric capacitor. The hydrophilic carbon electrode exhibits a superior capacitance (58 F cm-3, 99.3 mF cm-2) and is stable up to 5000 cycles. This journal is the Partner Organisations 2014.

A NEW CATALYTIC DETERMINATION OF COPPER(II) BY MEANS OF THE OXIDATIVE COUPLING REACTION OF p-HYDRAZINOBENZENESULFONIC ACID WITH m-PHENYLENEDIAMINE

A new sensitive catalytic method for the determination of copper(II) is proposed.In the presence of hydrogen peroxide, copper(II) catalyzes the oxidation of p-hydrazinobenzenesulfonic acid to p-sulfobenzenediazonium ion, which is coupled with m-phenylenediamine to form a yellow azo dye (λmax = 454 nm).By means of this catalytic reaction, nanogram amounts of copper(II) can be determined easily.

Synthesis of novel metal complexes of 2-((phenyl (2-(4-sulfophenyl) hydrazono) methyl) diazenyl) benzoic acid formazan dyes: Characterization, antimicrobial and optical properties studies on leather

We have developed novel formazan dyes (18–23) of enhanced fastness properties with cost-effectiveness in an aqueous system, without employing any Buffers and organic solvents. Their development was entailed of the synthesis of 2-((phenyl (2-(4-sulfophenyl) hydrazono) methyl) diazenyl) benzoic acid followed by the diazotization of 2-aminobenzoic acid that further reacted with the 4-[(2Z)-2-benzylidenehydrazinyl] benzene sulfonic acid. The multi-chromic (1:1 and 2:1) metal complexes of 2-((phenyl (2-(4-sulfophenyl) hydrazono) methyl) diazenyl) benzoic acid had been developed with the salts of Cr, Fe, Co, Cu and Ni; and they were characterized by elemental analysis, powder X-ray crystallography, Ultraviolet–visible, Fourier transforms infrared, Proton nuclear magnetic resonance and C13-nuclear magnetic resonance spectroscopic techniques. Density functional theory (DFT) studies of all dyes (18–23) were performed to evaluate the most stable geometries and structural parameters as well. The synthesized formazan dyes were evaluated for their different fastness (light, wash, perspiration), exhaustion and fixation properties on goat leather fabric and were revealed to have virtuous fastness properties (3–5, 4–5, 3–5, and 4–5) with high percentage value of exhaustion and fixation ranged from 91 to 97% and 90–98% respectively. The synthesized formazan dyes (18–23) were developed different colors such as Red, Brown, Green, Black, and Blue on leather. Synthesized formazan dyes were also evaluated for their antibacterial propensity on leather substrate and in solution by agar well diffusion method. The metal complex formazan dye (21) was demonstrated the significant bactericidal propensity against E. coli, S. aureus, Klebsiella and B. subtilis in solution and on leather by exhibiting maximum ZOIs (19 ± 0.05 mm, 25 ± 0.07 mm, 23 ± 0.09 mm, 27 ± 0.03 mm) and percentage reduction in bacterial growth (60 ± 0.03%, 69 ± 0.07%, 80 ± 0.05% and 86 ± 0.08%) respectively. Hence, newly synthesized formazan dyes (18–23) have efficient optical and antibacterial properties that would be proved valuable for the development of new industrial products to be commercialize.
