Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 611-73-4, Name is 2-Oxo-2-phenylacetic acid, molecular formula is , belongs to phthalazine compound. In a document, author is Kon, Hiroki, Electric Literature of 611-73-4.

Two ternary ligands consisting of two 2,2′:6′,2 ”-terpyridines and one N4-quadridentate mu(2),eta(2)-bridging ligand were synthesized. The N4 bridge is 1,4-bis(2-pyridyl)phthalazine in ligand 1, and 3,6-bis(2-pyridyl)pyridazine in ligand 2. Two Co(II) dinuclear complexes [(1)Co-2(mu-OH)](3+) and [(2)Co-2(mu-OH)](3+), and one Ni(II) dinuclear complex [(1)Ni-2(mu-Cl)](3+) were obtained. In the crystal structures of [(1)Co-2(mu-OH)](3+) and [(1)Ni-2(mu-Cl)](3+), two pyridine rings are twisted around the pyridine-phthalazine bonds to avoid steric repulsion between the hydrogen atoms. The pyridine rings also showed a significant tilt from the octahedral coordination plane, which causes the large positive shift of the first reduction potentials. Upon the addition of a proton, the cobalt dinuclear complexes can release one cobalt ion selectively, and the dinuclear complexes can be easily restored by the addition of a tertiary amine.

Electric Literature of 611-73-4, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 611-73-4 is helpful to your research.

Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout, creation and manufacturing process of chemical products and materials. Quality Control of 3-Ethyltoluene, 620-14-4, Name is 3-Ethyltoluene, SMILES is CC1=CC(CC)=CC=C1, in an article , author is El-Helby, Abdel-Ghany A., once mentioned of 620-14-4.

A new series of 2-substituted-2,3-dihydrophthalazine-1,4-diones (2 9) were designed and synthesized to evaluate their anticonvulsant activity. The neurotoxicity was assessed using the rotarod test. Molecular docking was performed for the synthesized compounds to assess their binding affinities as -aminobutyric acid A (GABA-A) receptor agonists as a possible mechanism of their anticonvulsant action, to rationalize their anticonvulsant activity in a qualitative way. The data obtained from the molecular modeling was strongly matched with that obtained from the biological screening, which revealed that compounds 5(a), 9(b), and 9(h) showed the highest binding affinities toward the GABA-A receptor and also showed the highest anticonvulsant activities with relative potencies of 1.66, 1.63, and 1.61, respectively, compared with diazepam. The most active compounds 5(a), 9(b), and 9(h) were further tested against maximal electroshock seizures. Compounds 5(a) and 9(b) showed 100% protection at a dose level of 125 mu g/kg, while compound 9(h) exhibited 83.33% protection at the same dose level. A GABA enzymatic assay was performed for these highly active compounds to confirm the obtained results and to explain the possible mechanism for their anticonvulsant action. These agents exerted low neurotoxicity and a high safety margin compared with valproate as a reference drug. Most of our designed compounds exhibited a good ADMET profile.

In this study, the structural properties, energetic data, and classification of the chemical properties of n,m-diazaphenanthrine derivatives were studied by a density functional theory (DFT) method. The important and proper indices were applied in this investigation. The structures, electronic properties, and chemical reactivities of 25 isomeric n,m-diazaphenanthrenes were studied by a B3LYP/6?31+G(d) method/basis set. All the optimized geometries of these isomers kept good planarity. The structural properties such as bond lengths and dipole moments of these isomers were calculated. The energies of frontier orbitals (HOMO and LUMO) are used to determine several chemical reactivity parameters as a measure of their relative stabilities. These include total energy (E), ionization potential (I), electron affinity (A), chemical hardness (?), chemical softness (S), electronic chemical potentials (?), and electrophilicity (?). Based on these calculations, the heats of formation (?H?(f)) for all the n,m-diazaphenanthrine derivatives are predicted. Benzo[h]quinazoline (P-13) and benzo[f]cinnoline (P-34) are calculated to be the most stable and the least stable isomers, respectively. 1,10-Phenanthroline (P-110) possesses the minimum electrophilicity, while benzo[c]cinnoline (P-56) is calculated to have the highest electrophilicity among the isomeric structures. The largest and smallest dipole moments are calculated for benzo[f]phthalazine (P-23) and 3,8-phenanthroline (P-38), respectively. Linear relationships between the calculated E-LUMO (in eV) values and electrophilicity (?) of the isomeric n,m-diazaphenanthrenes were observed.

New hydrophilic fluorescent selective ion sensor based on phenazine and phthalazine moieties, 1,1′-(phenazine-2,3-diyl)-bis(3-(1,4-dihydroxyphthalazin-6-yl)urea) (1), has been designed, synthesized and characterized. Interestingly, sensor 1 exhibits prominent turn-on and turn-off’ fluorogenic signaling at 580 nm towards Fe2+ & AcO- and Sr2+ & Cu2+, respectively. The fluorescence titration experiments shed light on the nature of the interaction between 1 and guest molecules (Fe2+, Sr2+, Cu2+ and AcO-), which divulge that 1 is flexible enough to orient itself according to the size of the guest molecule. Water mediated excited-state intramolecular proton transfer (ESIPT) and photo-induced electron transfer (PET) mechanisms are responsible for the dual behavior of 1, which binds with guest molecules in 1:1 stoichiometry, Based on the significant duplex fluorescence response of 1, a molecular logic gate keypad lock with sixteen on passwords for a storage system has been developed.
