1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.HPLC of Formula: 104-73-4

Synthesis and study of anisotropic ammonium salts for production of liquid-crystalline materials and devices with variable surface anchoring was written by Kuz’menok, N. M.;Mikhalyonok, S. G.;Arol, A. S.;Bezborodov, V. S.;Krakhalev, M. N.;Sutormin, V. S.;Prishchepa, O. O.;Zyryano, V. Ya.. And the article was included in Zhidkie Kristally i Ikh Prakticheskoe Ispol’zovanie in 2018.HPLC of Formula: 104-73-4 This article mentions the following:

This paper describes the various anisotropic quaternary ammonium salts characterized by a specific interaction with the interface and capable to form various orientational structures of liquid crystal layer, have been prepared It has been shown that these salts are promising materials for creation of advanced liquid crystal compositions with surface anchoring caused by ionic surfactants. The obtained results are of undoubted interest for the developers of new liquid crystal materials and electro-optical devices based on them. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4HPLC of Formula: 104-73-4).
