Iken, Hicham et al. published their research in Tetrahedron Letters in 2012 | CAS: 104-73-4

1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). 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.Computed Properties of C17H30BrN

Scalable synthesis of ionic liquids: comparison of performances of microstructured and stirred batch reactors was written by Iken, Hicham;Guillen, Frederic;Chaumat, Helene;Mazieres, Marie-Rose;Plaquevent, Jean-Christophe;Tzedakis, Theodore. And the article was included in Tetrahedron Letters in 2012.Computed Properties of C17H30BrN This article mentions the following:

A range of alkylpyridinium bromide ionic liquids have been synthesized in a stirred reactor at multigram scale and characterized by phys. methods (viscosity, conductivity, m.p., electrochem. window, and water content). One ionic liquid, octylpyridinium bromide, was chosen to be synthesized in both macro and reduced scale reactors, in order to compare its performance and to afford evidence of the advantages of a cross channel micro reactor (channel width = 1 mm) compared to a stirred reactor. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Computed Properties of C17H30BrN).
