The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. 104-53-0, Name is 3-Phenylpropanal, molecular formula is C9H10O, belongs to phthalazine compound. In a document, author is Pradhan, Koyel, introduce the new discover, Product Details of 104-53-0.

A SO3H-bearing carbonaceous solid catalyst has been synthesized through sulfonation followed by the hydrothermal carbonization method from renewable resource polyethylene glycol. The biodegradable catalyst was characterized by XRD, TEM, FT-IR, and energy dispersive X-ray. The surface area and pore diameter of the catalyst were determined by a nitrogen adsorption-desorption isotherm experiment. A highly efficient multicomponent heteroannulation protocol for the synthesis of a library of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives has been developed by applying the solid acid catalyst. This synthesis was established to follow the group-assistant-purification chemistry process avoiding traditional chromatography. The aqueous reaction medium, easy recovery of the catalyst, and high yield of the products make the protocol attractive, sustainable, and economic. This work may not only lead to environmentally benign systems, but also will provide a new aspect of organic chemistry in water.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 104-53-0 help many people in the next few years. Product Details of 104-53-0.

Formula: https://www.ambeed.com/products/104-53-0.html, While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards. 104-53-0, Name is 3-Phenylpropanal, SMILES is O=CCCC1=CC=CC=C1, belongs to phthalazine compound. In a article, author is Rha, Chang Joo, introduce new discover of the category.

A novel and effective phthalazine-imidazole-based colorimetric chemosensor (E)-1-(2-((1H-imidazol-2-yl)me-thylene)hydrazinyl)phthalazine NNI was synthesized and tested to detect Cu2+ or Co2+ ions in buffer solution. NNI could probe Cu2+ and Co2+ by the color change from colorless to yellow. The complexation stoichiometries of NNI toward Cu2+ and Co2+ were, respectively, confirmed to be as 1:1 ratio and 2:1 by results of Job plot and ESI-mass. Detection limits of NNI for each metal showed 0.12 mu M and 65 nM which are lower than WHO guideline (31.5 mu M for Cu2+) and US Environmental Protection Agency (EPA) guideline (1.7 mu M for Co2+). Quantification of NNI for each metal was successful in real water samples. The Cu2+-NNI complex could detect S2- by demetallation with color change from yellow to colorless, and detection limit for S2- was determined as 0.80 mu M, which is lower than WHO guideline (14.8 mu M). Cu2+-NNI could detect S2- without interference when other anions coexisted. Detection of Cu2+, Co2+ and S2- among various metal ions and anions was successfully confirmed using test papers stained with NNI and Cu2+-NNI. Sensing processes of Cu2+, Co2+ and S2- by NNI were elucidated by UV-vis titration, ESI-mass, FT-IR, H-1 NMR titration and DFT calculations.

A probe mediated SERS-based strategy is developed to selectively detect hydrazine with superb sensitivity. Ortho-phthaldialdehyde, a simple probe, reacts specifically with hydrazine to form phthalazine, a molecule that possesses a larger Raman cross section and better affinity toward the SERS substrate. We observed a limit of detection of 8.5 X 10(-11) M. Our method shows both qualitative and quantitative measurement of hydrazine with high sensitivity, low cost, and fast analysis time.

New phthalazine-based vasodilators were synthesized through the chloroacylation of the starting compound 1-hydrazinophthalazine 4 to give the two key intermediates 5 and 7. These intermediates were used to alkylate various cyclic amines to furnish the final compounds 6a-h and 8a-h. Compounds were tested for their vasorelaxant activities against nor-adrenaline-induced spasm on thoracic rat aorta rings and compared to the reference drug, prazosin. Seven compounds showed higher activity than prazosin, especially compound 8d having an IC50 = 0.10 mM. Molecular modeling studies, including fitting of the synthesized compounds to a 3D-pharmacophore and their docking into optimized homology model as alpha(1)-AR antagonists showed high docking score and fit values. Most vasodilation activities of tested compounds are consistent with their molecular modeling results. (C) 2012 Elsevier Masson SAS. All rights reserved.

A novel series of tacrine-like compounds 7a-u possessing a fused pyrazolo[1,2-b]phthalazine structure were designed and synthesized as potent and selective inhibitors of AChE. The in-vitro biological assessments demonstrated that several compounds had high anti-AChE activity at nano-molar level. The more promising compound 71 with IC50 of 49 nM was 7-fold more potent than tacrine and unlike tacrine, it was highly selective against AChE over BuChE. The cell-based assays against hepatocytes (HepG2) and neuronal cell line (PC12) revealed that 71 had significantly lower hepatotoxicity compared to tacrine, with additional neuroprotective activity against H2O2-induced damage in PC12 cells. This compound could also inhibit AChE-induced and self-induced A beta peptide aggregation. The advantages including synthetic accessibility, high potency and selectivity, low toxicity, adjunctive neuroprotective and A beta aggregation inhibitory activity, make this compound as a new multifunctional lead for Alzheimer’s disease drug discovery.

2,6-Di-tert-butyl-p-quinone 1′-phthalazynylhydrazone (HL) is synthesized; the total energies and geometry of the possible hydrazone tautomeric forms are calculated by quantum chemical methods. The hydrazone phthalazone tautomer is shown to be the most stable, which is well consistent with the H-1 NMR spectroscopic data for hydrazone. An X-ray crystallographic analysis is performed of the hydrazone-based Zn(II) trinuclear complex, in which zinc atoms are linked by the diazine bridge of the phthalazine cycle and two pivalate bridges. The geometric properties of the monodeprotonated hydrazone residue in the complex are similar to the calculated data for the phthalazone hydrazone tautomeric form.
