Li, Ying published the artcileHighly Sensitive Detection of Mercury Ions Using Zincophosphite Framework Nanoparticle-Polyaniline Composites, Recommanded Product: 3,5-Diamino-1,2,4-triazole, the main research area is mercury ions zincophosphite framework nanoparticle polyaniline composite.

This study reports a highly sensitive mercury ion sensor composed of the zincophosphite framework nanoparticle (NTOU4nano) blended with in situ synthesized conductive polyaniline (PANI). High stability of the pristine zincophosphite solid not only renders a facile nanosizing treatment feasible but also allows it to withstand the electrochem. PANI deposition at a low pH condition. PANI significantly enhances the surface coverage concentration and increases the electron transfer capability of the resulting composite. Cyclic voltammetry (CV), differential pulse voltammetry (DPV), hydrodynamic amperometry, and electrochem. impedance spectroscopy (EIS) are used to characterize and optimize the electroanal. performance of the nanocomposite. The resulting electrochem. sensor shows a linear dynamic range for mercury ion detection ranging from 0.05 to 27.5 nM and exhibits one of the lowest limits of detection (LODs) of 3.49 x 10-11 M reported using crystalline organic-inorganic hybrids. Addnl., the practical utility of the nanocomposite for mercury ion sensing is demonstrated using water samples containing high salt concentrations, as well as from the environment including the seawater and river water. In short, the reported nanocomposite is among one of the first metallophosphite materials being consolidated with PANI as an integrated sensing platform for highly sensitive mercury ion detection and holds good promise for early-warning application.

Calam, Tugba Tabanligil published the artcileElectrochemical Oxidative Determination and Electrochemical Behavior of 4-nitrophenol Based on an Au Electrode Modified with Electro-polymerized 3,5-diamino-1,2,4-triazole Film, Product Details of C2H5N5, the main research area is nitrophenol analysis water gold electrode diaminotriazole film.

A simple and fast electrochem. method was described and evaluated to determine the hazardous compound, 4-nitrophenol (4NP). In this work, concentration of 4NP was determined by differential wave voltammetry (DPV). A gold electrode (Au) was modified with 3,5-diamino-1,2,4-triazole (35DT). The modified electrode (35DT-Au) was characterized by using electrochem. impedance spectroscopy (EIS), fourier transform IR spectrophotometry (FTIR), cyclic voltammetry (CV) and DPV. The modified electrode showed more sensitivity towards 4NP compared to unmodified one. A wide linear concentration range from 0.24 to 130.6μM was obtained for 4NP with a detection limit of 0.09μM. In the reproducibility and repeatability studies, the relative standard deviation (RSD%) values of the method were obtained as 3.72% and 2.56%, resp., which are acceptable values. This proposed method was successfully used for the anal. of 4NP in lake and tap water samples. Simplicity, sensitivity, selectivity and high efficiency of the proposed method can be used in routine anal. of trace amounts of 4NP in polluted waters.

Chen, Xinyi published the artcileControlling Speciation during CO2 Reduction on Cu-Alloy Electrodes, Recommanded Product: 3,5-Diamino-1,2,4-triazole, the main research area is carbon dioxide reduction copper alloy ethylene Raman cupric oxide.

Electrodeposition of Cu, Cu/Ag, and Cu/Sn alloy films by using 3,5-diamino-1,2,4-triazole (DAT) as an electrodeposition inhibitor yields a high surface area Cu-based catalyst. All three Cu-based electrodes exhibit high Faradaic efficiency (FE) of CO2 reduction toward C2H4 production The CuSn-DAT electrode exhibits the highest FE for CO (∼90% at -0.4 V) and C2H4 (∼60% at -0.8 V) production and high c.d. (∼-225 mA/cm2 at -0.8 V). In situ surface enhanced Raman spectroscopy (SERS) studies in a flow cell obtained from the three Cu-based samples show a correlation between the decreased oxide content on the Cu surface, increased presence of CO, and increased activity for CO and C2 production The CuSn-DAT electrode has the lowest amount of Cu2O and exhibits the highest activity, whereas the Cu-DAT electrode has an increasing Cu2O content and exhibits lower activity as the potential is made neg. These results demonstrate that incorporation of different well-mixed alloy materials provides a way to tune CO2 reduction speciation.

Fonseca, Sarah published the artcileOxygen Reduction Reaction on a CuII Complex of 3,5-Diamino-1,2,4-triazole: A DFT Approach, Recommanded Product: 3,5-Diamino-1,2,4-triazole, the main research area is oxygen reduction reaction diaminotriazole copper complex electrocatalyst analysis.

The high costs for producing catalysts for fuel cells combined with low efficiency in oxygen reduction make metal-organic complexes a promising alternative to noble-metal catalysts. The electrochem. activity of Cu-complex-based catalysts has been reported by many authors, but only a few works are devoted to theor. studies. In this manuscript, d. functional theory (DFT) calculations are used to investigate the oxygen reduction reaction (ORR) on a CuII complex of 3,5-diamino-1,2,4-triazole. The determining steps for the associative and dissociative mechanisms are the oxygen adsorption and the oxygen bond cleavage, resp. The barrier for breaking the O-O bond in the dissociative mechanism was estimated at 0.7 eV.

Ribeiro, Carlos J. A. published the artcileTriazolopyrimidine and triazolopyridine scaffolds as TDP2 inhibitors, Name: 3,5-Diamino-1,2,4-triazole, the main research area is TDP2 inhibitors anticancer triazolo pyrimidines pyridines SAR; Anti-cancer; Triazolo-pyridines; Triazolo-pyrimidines; Tyrosyl-DNA phosphodiesterase 2 (TDP2).

Tyrosyl-DNA phosphodiesterase 2 (TDP2) repairs topoisomerase II (TOP2) mediated DNA damages and causes cellular resistance to clin. used TOP2 poisons. Inhibiting TDP2 can potentially sensitize cancer cells toward TOP2 poisons. Com. compound P10A10, to which the structure was assigned as 7-Ph triazolopyrimidine analog 6a, was previously identified as a TDP2 inhibitor hit in our virtual and fluorescence-based biochem. screening campaign. We report herein that the hit validation through resynthesis and structure elucidation revealed the correct structure of P10A10 (Chembridge ID 7236827) to be the 5-Ph triazolopyrimidine regioisomer 7a. Subsequent structure-activity relationship (SAR) via the synthesis of a total of 47 analogs of both the 5-Ph triazolopyrimidine scaffold (7) and its bioisosteric triazolopyridine scaffold (17) identified four derivatives (7a, 17a, 17e, and 17z) with significant TDP2 inhibition (IC50 < 50 μM), with 17z(I) showing excellent cell permeability and no cytotoxicity. Bioorganic & Medicinal Chemistry Letters published new progress about Antitumor agents (sensitize cancer cells). 1455-77-2 belongs to class isoquinoline, name is 3,5-Diamino-1,2,4-triazole, and the molecular formula is C2H5N5, Name: 3,5-Diamino-1,2,4-triazole.
