Oil-water distribution of p-alkylpyridines was written by Yeh, Kuang C.;Higuchi, William I.. And the article was included in Journal of Pharmaceutical Sciences in 1976.HPLC of Formula: 27876-24-0 This article mentions the following:
The distribution of a homologous series of p-alkylpyridines between water and six organic solvents with varying degrees of polarity was investigated. The distribution coefficients were considered as reflections of the strength of net interactions involved in the solvents. The order was chloroform > octanol > carbon tetrachloride > butyl ether > hexadecane > octane. The effect of the methylene group on the distribution coefficients differed little among the six solvents. The relative constancy was attributed to the predominance of the dispersion forces in the incremental effect. In the experiment, the researchers used many compounds, for example, 4-Hexylpyridine (cas: 27876-24-0HPLC of Formula: 27876-24-0).
4-Hexylpyridine (cas: 27876-24-0) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. 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: 27876-24-0
