13C NMR spectra of 2,4-dihalopicolines and their N-oxides and IR spectra of 2-halopicoline N-oxides, 2,4-dihalopicoline N-oxides and 2-halo-4-nitropicoline N-oxides was written by Puszko, A.. And the article was included in Polish Journal of Chemistry in 1992.Formula: C6H5Br2N This article mentions the following:
The 13C NMR and IR spectra of the title compounds were recorded and their spectral parameters assigned. The influence of electronic properties of the substituents on the direction of chem. shifts and νN-O values is discussed. The ratio between a substituted heterocyclic compound and its parent and the identically substituted benzene derivatives has been determined In the experiment, the researchers used many compounds, for example, 2,4-Dibromo-5-methylpyridine (cas: 79055-50-8Formula: C6H5Br2N).
2,4-Dibromo-5-methylpyridine (cas: 79055-50-8) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Formula: C6H5Br2N
