And the article contained the following:

The authors report a novel rare earth metal complex with the weak ligand of aromatic sulfonic acid (pyridine-3-sulfonic acid, 3-pSO3H), and characterized by FTIR, UV-visible, energy-dispersive x-ray spectroscopy (EDX), electrochemiluminescence spectra, etc. Then an excellent electrochemiluminescence (ECL) signal was observed with K2S2O8 as the coreactant in NaAc-HAc buffer solution For another thing, the electrochem. properties of the compound were thoroughly studied in MeCN solution, the possible ECL reaction mechanism is proposed as well. Also, a simple and straightforward ECL platform is reported for sensitive and selective detection of Cd2+ due to the effective quenching after addition of Cd2+. Other heavy/transition metal ions do not interfere with the sensing. The limit of detection is determined as 0.13 nM, the results suggested that as-prepared complex could be a promising material for developing ECL sensors to detect the Cd2+ rapidly indwell in environmental and practical samples. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Safety of Pyridine-3-sulfonic acid

On July 15, 2013, Duan, Lele; Wang, Lei; Inge, A. Ken; Fischer, Andreas; Zou, Xiaodong; Sun, Licheng published an article.Category: pyridine-derivatives The title of the article was Insights into Ru-Based Molecular Water Oxidation Catalysts: Electronic and Noncovalent-Interaction Effects on Their Catalytic Activities. And the article contained the following:

A series of Ru-bda water oxidation catalysts [Ru(bda)L2] (H2bda = 2,2′-bipyridine-6,6′-dicarboxylic acid; L = [HNEt3][3-SO3-pyridine], 1; 4-(EtOOC)-pyridine, 2; 4-bromopyridine, 3; pyridine, 4; 4-methoxypyridine, 5; 4-(Me2N)-pyridine, 6; 4-[Ph(CH2)3]-pyridine, 7) were synthesized with electron-donating/-withdrawing groups and hydrophilic/hydrophobic groups in the axial ligands. These complexes were characterized by 1H NMR spectroscopy, high-resolution mass spectrometry, elemental anal., and electrochem. In addition, complexes 1 and 6 were further identified by single crystal X-ray crystallog., revealing a highly distorted octahedral configuration of the Ru coordination sphere. All of these complexes are highly active toward CeIV-driven (CeIV = Ce(NH4)2(NO3)6) water oxidation with oxygen evolution rates up to 119 mols of O2 per mol of catalyst per s. Their structure-activity relationship was investigated. Electron-withdrawing and noncovalent interactions (attraction) exhibit pos. effect on the catalytic activity of Ru-bda catalysts. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Category: pyridine-derivatives

Only complex 2d was water-soluble (>2 mmol L-1); 2c is soluble in water/2-propanol mixtures In toluene as a reaction medium, only the relatively weakly coordinated tertiary amine complex 2b is polymerization active (1.7 × 104 TO). In aqueous systems 2c,d are also active due to compartmentalization of the active site in the polymer particles and of L in the aqueous phase. Polyethylene particle sizes vary from 18 nm (dispersions formed with 2d) to over 0.5 μm (2c) to suspensions (2b) depending on the initial state of the reaction mixture, correlated with catalyst solubility The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Quality Control of Pyridine-3-sulfonic acid

And the article contained the following:

High catalytic activities (TO = 000 -1) have been achieved by novel water-soluble ruthenium catalysts modified with nitrogen-containing ligands such as the bathophenanthrolinedisulfonic acid disodium salt (BPhDS) in the hydrogenation reaction of the renewable polar platform chem. levulinic acid (LA) which possesses a central relevance in the development of biorefineries of the future in a sustainable way to produce with essentially quant. selectivity of 99.9 mol% γ-valerolactone (GVL) in aqueous media. The apparent activation energy of the Ru/BPhDS catalyst was calculated and amounts a relative low value of 53.3 J/mol when one considers that in the LA hydrogenation reaction this catalyst reduces a less reactive keto group into alc. functionality. A recycling experiment of the Ru/BPhDS catalyst by extraction after addition of di-Et ether has shown that the catalyst is stable without loss of activity and selectivity in a consecutive run. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Product Details of 636-73-7
