Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 767-69-1, Name is 6-Bromo-7H-purine, molecular formula is C5H3BrN4, belongs to piperidines compound, is a common compound. In a patnet, author is Wardell, James L., once mentioned the new application about 767-69-1, Name: 6-Bromo-7H-purine.
Racemic mefloquinium chlorodifluoroacetate: crystal structure and Hirshfeld surface analysis
In the racemic title molecular salt, C17H17F6N2O+center dot C2ClF2O3-(systematic name: 2-{[2,8-bis(trifluoromethyl) quinolin-4-yl](hydroxy) methyl} piperidin-1-ium chlorodifluoroacetate), the cation, which is protonated at the piperidine N atom, has the shape of the letter, L, with the piperidin-1-ium group being approximately orthogonal to the quinolinyl residue [the C-q-C-m-C-m-N-a (q = quinolinyl; m = methine; a = ammonium) torsion angle is 177.79 (18)degrees]. An intramolecular, charge-assisted ammonium-N-H center dot center dot center dot O(hydroxyl) hydrogen bond ensures the hydroxy-O and ammonium-N atoms lie to the same side of the molecule [O-h-C-m-C-m-N-a (h = hydroxyl) = -59.7 (2)degrees]. In the crystal, charge-assisted hydroxyl-O-H center dot center dot center dot O- (carboxylate) and ammonium-N+-H center dot center dot center dot O-(carboxylate) hydrogen bonds generate a supramolecular chain along [010]; the chain is consolidated by C-H center dot center dot center dot O interactions. Links between chains to form supramolecular layers are of the type C-Cl center dot center dot center dot pi (quinolinyl-C-6) and the layers thus formed stack along the a-axis direction without directional interactions between them. The analysis of the calculated Hirshfeld surface points to the dominance of F center dot center dot center dot H contacts to the surface (40.8%) with significant contributions from F center dot center dot center dot F (10.5%) and C center dot center dot center dot F (7.0%) contacts.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 767-69-1. The above is the message from the blog manager. Name: 6-Bromo-7H-purine.
