In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Crystal structure of the thalidomide analog (3aR*,7aS*)-2-(2,6-dioxopiperidin-3-yl)hexahydro-1H-isoindole-1,3(2H)-dione, published in 2018-11-01, which mentions a compound: 610-09-3, Name is cis-Cyclohexane-1,2-dicarboxylic acid, Molecular C8H12O4, Recommanded Product: 610-09-3.

The title compound, C13H16N2O4, crystallizes in the monoclinic centrosym. space group, P21/c, with four mols. in the asym. unit, thus there is no crystallog. imposed symmetry and it is a racemic mixture The structure consists of a six-membered unsaturated ring bound to a five-membered pyrrolidine-2,5-dione ring N-bound to a six-membered piperidine-2,6-dione ring and thus has the same basic skeleton as thalidomide, except for the six-membered unsaturated ring substituted for the aromatic ring. In the crystal, the mols. are linked into inversion dimers by R22(8) hydrogen bonding involving the N-H group. In addition, there are bifurcated C-H···O interactions involving one of the O atoms on the pyrrolidine-2,5-dione with graph-set notation R12(5). These interactions along with C-H···O interactions involving one of the O atoms on the piperidine-2,6-dione ring link the mols. into a complex three-dimensional array. There is pseudomerohedral twinning present which results from a 180° rotation about the [100] reciprocal lattice direction and with a twin law of 1 0 0 0 [inline formula omitted] 0 0 0 [inline formula omitted] [BASF 0.044 (1)].

Synthetic Route of C5H6N2O2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 2-Furoic hydrazide, is researched, Molecular C5H6N2O2, CAS is 3326-71-4, about Synthesis, structural characterization, and computational study of (E)-N’-(3,4-dimethoxybenzylidene)furan-2-carbohydrazide. Author is Mkadmh, Ahmed M.; Morjan, Rami Y.; Raftery, James; Awadallah, Adel M.; Gardiner, John M..

An efficient synthesis of the new (E)-N’-(3,4-dimethoxybenzylidene)furan-2-carbohydrazide is described. Its mol. structural features have been characterized by single crystal X-ray diffraction. Quantum chem. calculations including mol. geometry, intermol. H-bonds and vibrational frequencies were carried out for the structures to explain stability and geometry using the hybrid d. functional (DFT/B3LYP) in conjunction with 6-311 + G(d,p) basis set. The calculated structural and vibrational parameters are presented and compared with their exptl. X-ray and FTIR counterparts. The global min. and local min. ground states characteristics of the title compound and its rotamers have been theor. established through 2D potential energy scan and vibrational frequencies. Computational anal. predicted that head-to-tail E/E-dimer of the observed E-isomer has significantly stronger intermol. hydrogen bonding in solution rather than in the gaseous state. It is found that N-H and C=O vibrational bands suffering blue-shift due to intermol. hydrogen bonds (IHBs). Weak intramol. hydrogen bonds that have been detected in the monomeric form in the gaseous state and in solution are lacking in trimers and tetramers due to loss of planarity in the mol. structure. Optimization in solution clearly shows that the strength of the IHBs decreased exponentially with dielec. continuum of the solvent used. Inexistence of solvent/monomer intermol. hydrogen bonds has been explained in terms of Condensed Fukui Functions.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Validation Study, Electrophoresis called Positional and geometrical anionic isomer separations by capillary electrophoresis-electrospray ionization-mass spectrometry, Author is Nogami, Chika; Sawada, Hirokazu, which mentions a compound: 610-09-3, SMILESS is O=C([C@H]1[C@@H](C(O)=O)CCCC1)O, Molecular C8H12O4, Product Details of 610-09-3.

Capillary electrophoresis-electrospray ionization-mass spectrometry (CE-ESI-MS) was applied to the anal. of polar positional and geometrical anionic isomers. Since the studied positional and geometrical anionic isomers have different pKa values, they could be separated by CE-ESI-MS under simple anal. conditions using a bare fused-silica capillary and volatile ammonium acetate buffer after optimizing buffer pH. Ortho-, meta-, para-hydroxybenzoate positional isomers were completely separated on a fused-silica capillary with 20 mM ammonium acetate buffer at pH 10.0, and cis-, trans-cyclohexane dicarboxylate geometrical isomers could be also separated with 20 mM ammonium acetate buffer at pH 4.0. Several anal. parameters affecting ESI-MS sensitivity were also studied. Both running buffer pH and sheath liquid pH had significant effects on the selectivity and the sensitivity on CE-ESI-MS anal. while sheath flow rate and other parameters had little influence. Under optimized conditions, linearity, detection limit, and repeatability of the anal. of hydroxybenzoate isomers were examined, and good results were obtained. The method presented in this paper is a simple, robust, and cost-effective method for simultaneous anal. of positional and geometrical anionic isomers and of other small anionic compounds

Quality Control of 2-Furoic hydrazide. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2-Furoic hydrazide, is researched, Molecular C5H6N2O2, CAS is 3326-71-4, about Investigation of DNA interaction and antiproliferative activity of mixed ligand dioxidomolybdenum(VI) complexes incorporating ONO donor aroylhydrazone ligands. Author is Dinda, Rupam; Panda, Arpita; Banerjee, Atanu; Mohanty, Monalisa; Pasayat, Sagarika; Tiekink, Edward R. T..

Four new mixed ligand dioxidomolybdenum(VI) [MoVIO2L1-3(Q)] (1-3), [MoVIO2L4(Q)]2 (H2O) (4) [where Q = MeOH for 1 and imidazole for 2-4] complexes were synthesized using four different ONO donor aroylhydrazone ligands (H2L1-4). All the derived ligands and complexes were characterized by different physicochem. techniques, i.e., elemental anal., spectroscopic methods (UV-Vis, NMR and IR), and cyclic voltammetry. The mol. geometries of 1-4 were established by X-ray crystallog. which reveals the Schiff base ligands coordinate – the distorted octahedral metal centers in a di-neg. tridentate fashion. The complexes indicated moderate binding affinity (103 to 104 M-1) towards CT-DNA. Further, in vitro cytotoxicity activity of all the complexes were determined against HT-29 (colon cancer) and HeLa (cervical cancer) cell lines. Complex 4, due to the presence of a heterocyclic 2-hydroxy-1-naphthyl moiety in the ligand backbone, was found to be more biol. active in comparison to the others in the series.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: cis-Cyclohexane-1,2-dicarboxylic acid, is researched, Molecular C8H12O4, CAS is 610-09-3, about Electrical property improvement of dicyandiamide-cured electrically conductive adhesives through in-situ replacement by difunctional acids and the impact on storage, the main research direction is dicyandiamide cured elec conductive adhesive difunctional acid storage.Synthetic Route of C8H12O4.

To improve the elec. conductivity of the dicyandiamide-cured elec. conductive adhesives (ECAs), short-chain difunctional acids with various structures including oxalic acid, succinic acid, adipic acid, phthalic acid and cis-hexahydrophthalic acid were introduced in-situ to replace the commonly used surfactant-stearic acid on the silver filler surface. Oxalic acid, phthalic acid and cis-hexahydrophthalic acid deteriorated the elec. conductivity of ECAs whereas the elec. conductivity was improved significantly with the addition of succinic acid and adipic acid. Moreover, the storage performance, viscosity, curing behavior, bulk resistivity and the shear strength of ECAs with varied content of adipic acid had been further studied. With the increment of adipic acid, the curing temperature of ECAs decreased, while the reaction between dicyandiamide and adipic acid happened as the content reached 0.3 wt%. And the adipic acid not just improved the elec. conductive, but also improved the shear strength without adversely affected the storage performance of ECAs. As the content of adipic acid reached 0.3 wt%, the lowest bulk resistivity 3.8×10-4 Ω cm was obtained, at the content of 0.5 wt%, the shear strength was improved to 18.5 MPa.
