Investigation of dynamic surface tension of aqueous solutions of cetyl- and dodecylpyridinium bromide by the oscillating jet method was written by Abdulin, N. G.;Kochurova, N. N.;Povysheva, N. I.;Temkin, A. S.. And the article was included in Vestnik Sankt-Peterburgskogo Universiteta, Seriya 4: Fizika, Khimiya in 2002.Reference of 104-73-4 This article mentions the following:
The dynamic surface tension of aqueous solutions of cetyl- and dodecylpyridinium bromide at different concentrations and temperatures 10-25°C has been measured. In these experiments a temperature inversion of the dynamic surface tension is observed for fresh surfaces. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Reference of 104-73-4).
1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Reference of 104-73-4
