Electric dipole moments of 2,4-dihalopicolines and their N-oxides was written by Puszko, A.. And the article was included in Chemical Papers in 1990.Electric Literature of C6H5Br2N This article mentions the following:
Dipole moment values of 2,4-dichloro- and 2,4-dibromopicolines and their N-oxides were calculated from the permittivity and refractive indexes measurements as well as by means of composition of groups and bonds moments vectors. The influence of substituents effects on the dipole moment values was discussed and the results obtained were compared. In the experiment, the researchers used many compounds, for example, 2,4-Dibromo-5-methylpyridine (cas: 79055-50-8Electric Literature of 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. Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties. Electric Literature of C6H5Br2N
