Tupitsyn, I. F.; Zatsepina, N. N.; Kolodina, N. S.; Kirova, A. V. published the artcile< Nuclear quadrupole resonance and infrared spectroscopic studies of electron interactions in polysubstituted azines>, HPLC of Formula: 6554-61-6, the main research area is NQR nitrogen heterocycle chlorine; pyridine pyrimidine NQR IR; substituent effect NQR IR pyridine.
35Cl NQR frequencies (νCl) and integral intensities (A) of ir absorption bands of stretching vibrations of aromatic C-H bonds of polysubstituted N heterocycles, e.g., chloropyridines, chloropyrimidines, were correlated with inductive and resonance substituent constants Electronic effects of the heteroatoms and substituents on νCl and A were additive.
Reaktsionnaya Sposobnost Organicheskikh Soedinenii published new progress about IR spectra. 6554-61-6 belongs to class pyrimidines, and the molecular formula is C4H2Cl2N2, HPLC of Formula: 6554-61-6.
