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. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Application of 104-73-4

Adsorption and micellization in solutions of dodecylpyridinium bromide-nonionic surfactant mixtures was written by Kharitonova, T. V.;Ivanova, N. I.;Summ, B. D.. And the article was included in Colloid Journal (Translation of Kolloidnyi Zhurnal) in 2002.Application of 104-73-4 This article mentions the following:

Dependences of the surface tension of aqueous solutions of cationic (dodecylpyridinium bromide) and nonionic (Tween 80, Triton X-100) surfactants and their mixtures on total surfactant concentration and solution composition were studied. The values of critical micellization concentration (CMC) and excess free energy of adsorption were determined from tensiometric measurements. Based on Rubingh-Rosen model (approximation of the theory of regular solutions), the compositions of micelles and adsorption layers at the solution-air interface as well as parameters of interaction between the mols. of cationic and nonionic surfactants were calculated for the systems indicated above. It was established that, in the case of surfactant mixtures with considerable difference in the CMCs, the micelles of individual surfactant with lower CMC value are formed. The effect of neg. deviation from the ideality during the adsorption of surfactants from mixed solutions at the solution-air interface was disclosed. It was shown that the interaction energy depends significantly on the composition of mixed systems. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Application of 104-73-4).
