In an article, author is Huang, Jian-Qiang, once mentioned the application of 5813-64-9, Name is 2,2-Dimethylpropan-1-amine, molecular formula is C5H13N, molecular weight is 87.1634, MDL number is MFCD00008134, category is amides-buliding-blocks. Now introduce a scientific discovery about this category, Computed Properties of https://www.ambeed.com/products/5813-64-9.html.

The report describes the effect of TiO2 nano particles on the hydrogenation characteristics of promising Li-Mg-N-H hydrogen storage system. The effect of different particle size of TiO2 (200, 25 and 7 nm) on de/re-hydrogenation characteristics of Mg(NH2)(2)/LiH mixture has been investigated. Desorption kinetics of Li-Mg-N-H system with 25 nm TiO2 gets enhanced upto similar to 25% as compared to the pristine material kinetics at 453 K (180 degrees C). The report also deals mechanistic approach for hydrogen release from Li-Mg-N-H system in the presence of TiO2 nanoparticles through XPS analysis of catalyzed sample at various stages of reaction. The XPS analysis confirms that during dehydrogenation nitrogen atom present in Li-Mg-N-H system share their lone pair electrons to Ti (present in TiO2) and provides an alternate decomposition path which has lower activation energy for dehydrogenation.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 615-05-4, Name is 4-Methoxybenzene-1,3-diamine, molecular formula is C7H10N2O. In an article, author is Wu, Jun-Yi,once mentioned of 615-05-4, Name: 4-Methoxybenzene-1,3-diamine.

Chemical investigation of a co-culture of two endophytic fungi Aspergillus fumigatus D and Fusarium oxysporum R1 from two traditional medicinal plants, Edgeworthia chrysantha Lindl. and Rumex madaio Makino, led to isolation of a new amide 1 and six known compounds, including neovasinin (2), neovasifuranone B (3), N-(2-phenylethyl)acetamide (4), alpha-linolenic acid (5), alpha-elaeostearic acid (6), palmitoleic acid (7). On the basis of extensive spectroscopic analysis including 1D and 2D NMR, HR-ESI-MS and optical rotation measurement as well as comparison of literature data, chemical structure of 1 was unambiguous elucidated as (S, E)-methyl-2-(2,4-dimethylhex-2-enamido)acetate. Bioassay results indicated that none of these compounds exhibited strong inhibitory effect on three human pathogens Escherichia coli, Staphyloccocus aureus and Candida albicans with MIC values of >= 25 mu M.

Application of 61-90-5, The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 61-90-5, Name is H-Leu-OH, SMILES is CC(C)C[C@H](N)C(O)=O, belongs to amides-buliding-blocks compound. In a article, author is Bhat, Chinmay, introduce new discover of the category.

Permanganate oxidizable carbon (POXC) is a sub-pool of labile soil organic carbon (SOC) and is defined as the carbon (C) that can be oxidized by potassium permanganate (KMnO4). Determination of the content of POXC has been used as a way to measure labile C and may be related to soil microbial biomass and particulate organic C. Fourier transform mid-infrared photoacoustic spectroscopy (FTIR-PAS) has been used for characterizing the chemical composition of soil organic matter. The objective of the current study was to identify the chemical information in the FTIR-PAS spectra that is unique to POXC and therefore associated with labile C. FTIR-PAS was used for characterizing SOC using a set of soil samples collected in four different countries (Laos, Malaysia, Peru and Thailand, n = 575). Partial least squares (PLS) regression was used to correlate the collected FTIR-PAS spectra with both POXC and total SOC. The FTIR-PAS spectra combined with the PLS method was useful for predicting both SOC and POXC. However, SOC and POXC were also highly correlated (R-2 = 0.84), and because POXC can be seen as a fraction of total SOC, a method for extracting the FTIR-PAS fingerprint of the POXC model that is independent of SOC was applied for the first time. The results showed that the POXC prediction was mainly based on its strong correlation with SOC and there was little information unique to POXC. However, the results do indicate four dominant peaks at 1,574, 1,495, 1,138 and 1,041 cm(-1) to be specific for POXC. These peaks can be ascribed to amide II, aromatics, polysaccharides and carbohydrates, respectively. Highlights Permanganate oxidizable carbon (POXC) was predicted using FTIR-photoacoustic spectroscopy (FTIR-PAS). The POXC prediction using FTIR-PAS is mainly based on its high correlation with SOC. A method extracting the unique spectral features of POXC independently of SOC was applied. Around 11% of the information used to predict POXC was identified as unique. Four dominant peaks were found to represent the POXC fingerprint.

Chemistry, like all the natural sciences, Recommanded Product: 2-(1-Methylguanidino)acetic acid, begins with the direct observation of nature— in this case, of matter.57-00-1, Name is 2-(1-Methylguanidino)acetic acid, SMILES is O=C(O)CN(C)C(N)=N, belongs to amides-buliding-blocks compound. In a document, author is Kutil, Zsofia, introduce the new discover.

In this work, poly(methacrylated vanillin) (PMV) was investigated for its reactivity in multicomponent reactions as a reactive polymer that can be sourced from lignin-based components. To achieve sustainable polymer chemistry, the PMV reactivity in a Passerini three-component reaction (Passerini-3CR) was investigated because the reactants in the Passerini-3CR can be abundantly sourced from biobased compounds. First, the Passerini-3CR of the PMV in solution phases revealed that the PMV pendant aldehydes can be converted into the corresponding alpha-acyloxy amides with >90% conversions under the optimized conditions. Taking advantage of this high reactivity of PMV, its immobilized cellulose fabric (Cell-g-PMV), a wood biomass-sourced organic hybrid, was subjected to the Passerini-3CR. Although the aldehydes were not completely converted, the PMV segments surrounding the fabric surfaces successfully reacted via the Passerini-3CR to engraft carboxylic acid and isocyanide components on the cellulose-based fabrics.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 57-00-1. Recommanded Product: 2-(1-Methylguanidino)acetic acid.

Reference of 2419-56-9, Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 2419-56-9, Name is H-Glu(OtBu)-OH, SMILES is [H][C@](N)(CCC(=O)OC(C)(C)C)C(O)=O, belongs to amides-buliding-blocks compound.

The complexation of hexavalent plutonyl Pu(vi) with N,N,N,N-tetramethyl-3-oxa-glutar-amide (TMOGA) and its carboxylate analogs, N,N-dimethyl-3-oxa-glutaramic acid (DMOGA) and oxydiacetic acid (ODA), has been studied in 1.0 M NaClO4 by absorption spectrophotometry and density functional theory (DFT). Both 1:1 and 1:2 complexes of Pu(vi) with TMOGA, DMOGA and ODA have been identified and their stability constants were obtained and compared with those of hexavalent U(vi) and pentavalent Np(v). The resultant stability constants indicate that the ability of the three ligands to complex with Pu(vi) decreases in the order of ODA > DMOGA > TMOGA. While for one given ligand, the stability constants of both the 1:1 and 1:2 complexes decrease generally in the order U(vi) > Pu(vi) > Np(v). The trends of the complexation strength have been elucidated by the calculated Mulliken atomic charges of the central metal cations. Furthermore, the coordination modes of the Pu(vi) complexes with TMOGA, DMOGA and ODA have been illustrated by analyses of the optical features of the complexes as well as by DFT calculations. The results demonstrate that the 1:2 Pu(vi)/TMOGA complex is centrosymmetric, while the 1:2 complexes of Pu(vi) with DMOGA and ODA are non-centrosymmetric. Moreover, different coordination modes have been observed in actinyl complexes with the same ligand, suggesting the structurally similar actinyl ions (U(vi), Pu(vi) and Np(v)) could exhibit quite different coordination behavior due to the variation of cation size and electronic structure.

Ginkgo biloba extract (GBE), derived from the leaves of Ginkgo biloba L, is one of the most widely used traditional Chinese medicines worldwide. Due to high structural diversity and low abundance of chemical constituents in GBE, conventional reversed-phase liquid chromatography has limited power to meet the needs of its quality control. In this study, an off-line hydrophilic interaction x reversed-phase two-dimensional liquid chromatography (HILIC x RP 2D-LC) system coupled with diode array detection (DAD) and quadrupole time-of-flight mass spectrometry (qTOE-MS) was established to comprehensively analyze the chemical constituents of GBE. After optimizing the chromatographic columns and mobile phase of 2D-LC, a Waters XBridge Amide column using acetonitrile/water/formic acid as the mobile phase was selected as the first dimension to fractionate GBE, and the obtained fractions were further separated on an Agilent Zorbax XDB-C18 column with methanol/water/formic acid as the mobile phase. As a result, a total of 125 compounds were detected in GBE. The orthogonality of the 2D-LC system was 69.5%, and the practical peak capacity was 3864 and 2994, respectively, calculated by two different methods. The structures of 104 compounds were tentatively characterized by qTOE-MS analysis, and 21 of them were further confirmed by comparing with reference standards. This established HILIC x RP 2D-LC-qTOF/MS system can greatly improve the separation and characterization of natural products in GBE or other complicated herbal extracts. (C) 2017 Elsevier B.V.

Metal oxide nanoparticles (NPs) stabilized by porous carbon materials (PCMs) are very promising for catalysis. In this work, monodispersed small and stable copper oxide (CuO) NPs were prepared with an average size of 10-20 nm without using any capping agent and then these NPs were encapsulated into porous carbon. The chemical and structural properties of the CuO/PCM material were characterized by powder X-ray diffraction, electron microscopy, Raman spectroscopy, scanning electron microscopy, transmission electron microscopy, and nitrogen sorption. The obtained CuO/PCM nanocatalytic system has been used for the synthesis of N-arylamides from the reaction of aldoximes and aryl halides. Generally, copper(II) salt was used for the preparation of amides from aldoximes using some ligands and bases, but harsh reaction condition, stoichiometric amount of metal, and lack of recyclability limit their applications in industry. An alternative method is the use of heterogeneous catalysts. More importantly, these heterogeneous catalysts could be easily recycled and reused, showing potential application in organic synthesis.
