Tsutsumi, Hiroyuki published the artcileMolecular capture using the precipitate of creaming-down by (-)-epigallocatechin-3-O-gallate, Product Details of C6H4N2, the main research area is epigallocatechin gallate chloropyrimidine crystal structure hydrogen bond mol capture; (â?-epigallocatechin-3-O-gallate; 2-chloropyrimidine; X-ray crystallographic analysis; creaming-down; quantitative 1H-NMR.
An aqueous solution of equimol. amounts of 2-chloropyrimidine and (-)-epigallocatechin 3-O-gallate (EGCg) afforded a colorless block crystal, which was determined to be a 2 : 2 complex of 2-chloropyrimidine and EGCg by X-ray crystallog. anal. The 2 : 2 complex was formed by the cooperative effect of three intermol. interactions, π-π and CH-π interactions, and intermol. hydrogen bonds. Upon formation of the 2 : 2 complex, a 2-chloropyrimidine mol. was captured by a hydrophobic space formed by the three aromatic rings of A, B, and B’ rings of two EGCg mols. The mol. capture abilities of various heterocyclic compounds using EGCg were evaluated by ratio of the heterocyclic compounds included in the precipitates of complex of EGCg to the heterocyclic compounds used. The amount of the heterocyclic compounds was measured by an integrated value of corresponding proton signals in the quant. 1H-NMR spectrum.
Chemical & Pharmaceutical Bulletin published new progress about Bond angle (hydrogen bond). 100-70-9 belongs to class nitriles-buliding-blocks, name is Picolinonitrile, and the molecular formula is C6H4N2, Product Details of C6H4N2.
