Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. 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, SDS of cas: 499-40-1
The preparation, characterization and crystal structures of the mono(dpyam) copper(II)nitrato complexes [Cu(dpyam)(O2NO)2] (1) and [Cu(dpyam)(O2NO)2]·2H2O (2) (dpyam = di-2-pyridylamine) have been investigated. Compound 1 consists of two crystallographically independent [Cu(dpyam)(O2NO)2] neutral molecules. These molecules are linked into infinite chains by the bridging bidentate nitrate groups in the long-bonded tetragonal positions giving an elongated rhombic octahedral stereochemistry. The structure of 2 is composed of a couple of crystallographically independent [Cu(dpyam)(O2NO)2] neutral molecules and four water molecules in the lattice. Each copper atom exhibits a tetrahedrally distorted square base of the N2O2 plane, with the second oxygen atoms of the monodentate nitrato groups weakly bound in nearly axial positions giving an extremely distorted octahedral coordination geometry.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.SDS of cas: 499-40-1. You can get involved in discussing the latest developments in this exciting area about 499-40-1
