Tsujimoto, Toshio; Nomura, Toshiro; Iifuru, Makiko; Sasaki, Yoshio published the artcile< Studies on carbon-13 magnetic resonance spectroscopy. XIII. Carbon-13 and proton NMR of 4-substituted pyridazine and 2-substituted pyrazine derivatives>, Recommanded Product: Pyridazin-4-amine, the main research area is NMR carbon pyridazine pyrazine derivative; substituent constant pyridazine pyrazine derivative.
13C NMR chem. shifts of 4-substituted pyridazines and 2-substituted pyrazines, together with 1H chem. shifts of the former compounds were measured. Linear correlations of the 13C and 1H chem. shifts of 4-substituted pyridazines with those of monosubstituted benzenes and monosubstituted pyridines and with substituent constants σπ were found. In addition, similar trends were noted for 2-substituted pyrazines. Chem. shifts of pyridazines and pyrazines can be predicted on the basis of these relationships.
Chemical & Pharmaceutical Bulletin published new progress about NMR (nuclear magnetic resonance). 20744-39-2 belongs to class pyridazine, and the molecular formula is C4H5N3, Recommanded Product: Pyridazin-4-amine.
