Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, new energy materials, preparation and modification of special coatings, and research on the structure and performance of functional materials499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11. In a Article，once mentioned of 499-40-1, Recommanded Product: (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal
The reactions of Al(CH3)3 with di-2-pyridylamine (dpaH) yielded a mononuclear zwitterion complex, Al(CH3)2(dpa) (1), a dinuclear complex, Al2(CH3)5(dpa) (2), and a tetranuclear complex, Al4(O)2(CH3)6(dpa)2 (3), depending on the stoichiometry and conditions of the reactions. The crystal structures of all three compounds were determined by single-crystal X-ray diffraction analyses. All three compounds emit an intense blue color in solution and the solid state at lambdamax = 475, 445, and 450 nm, respectively, when irradiated by an UV light. Molecular orbital calculations using ab initio methods (Gaussian 94) on dpa, dpaH, and compound 1 were performed which revealed that the aluminum ion in compounds 1-3 plays a key role in stabilizing the complexes and promoting the blue luminescence. The reaction of Al(CH3)3 with 2-pentafluoroanilinopyridine (pfapH) resulted in the formation of a mononuclear octahedral complex, Al(pfap)3 (4). Variable-temperature and COSY 1H NMR established that compound 4 is highly fluxional in solution due to a rapid interconversion of mer and fac isomers, with the mer isomer dominating at low temperature. The structure of the fac isomer of 4 was determined by X-ray diffraction. Compound 4 emits at lambdamax = 409 nm when irradiated by an UV light.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Recommanded Product: (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal. This is the end of this tutorial post, and I hope it has helped your research about 499-40-1
