2-Methyl-1,3-propanediol 99 2163-42-0 - Sigma-Aldrich
WebThe Phen-1,3-diol, 4,5,6-trimethoxy-2-propionyl- molecule contains a total of 34 bond (s) There are 18 non-H bond (s), 7 multiple bond (s), 5 rotatable bond (s), 1 double bond (s), 6 aromatic bond (s), 1 six-membered ring (s), 1 ketone (s) (aromatic), 2 aromatic hydroxyl (s) and 3 ether (s) (aromatic). WebThe NMR shifts of hydrogen-bonded protons in individual conformers of alkane-1,n-diols show a very rough correlation with the OH⋯OH distances. The computed overall NMR shifts for CH protons in 1,2- and 1,3-diols are systematically high but correlate very well with the experimental values, with a gradient of 1.07 ± 0.01. new this
