Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. The appropriate choice can avoid electrode passivation, which strongly inhibit the efficient activation of substrates. 499-40-1, 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, Application of 499-40-1
Halogenido and carboxylato Ru(II) half-sandwich complexes of the general composition [Ru(eta6-p-cym)(dpa)X]PF6 (1-5) were prepared and thoroughly characterized with various techniques (e.g., mass spectrometry, NMR spectroscopy and X-ray analysis); dpa = 2,2?-dipyridylamine; p-cym = p-cymene; X = Cl- (for 1), Br- (for 2), I- (for 3), valproate(1-) (for 4) or 4-phenylbutyrate(1-) (for 5). A single-crystal X-ray analysis showed a pseudo-octahedral piano-stool geometry of [Ru(eta6-p-cym)(dpa)I]PF6 (3), with a eta6-coordinated p-cymene, bidentate N-donor dpa ligand and iodido ligand coordinated to the Ru(II) atom. The results of the 1H-NMR solution behaviour studies proved that the complexes 1-5 hydrolyse were in the mixture of solvents used (10% MeOD-d4/90% D2O). Complexes 1-5 were in vitro inactive against the A2780 human ovarian carcinoma cell line, up to the highest tested concentration (IC50 > 100 muM).
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 499-40-1, help many people in the next few years., Related Products of 499-40-1
