Towards rigid-rod polyelectrolytes via well-defined precursor poly(p-phenylene)s substituted by 6-iodohexyl side chains was written by Rau, I. U.;Rehahn, M.. And the article was included in Acta Polymerica in 1994.Quality Control of 1-Bromo-6-methoxyhexane This article mentions the following:
A synthetic strategy is presented to prepare readily soluble poly-p-phenylene (PP) electrolytes of well-defined mol. constitution and conveniently determinable d.p. PP having 6-phenoxyhexyl pendant groups is treated with Me3SiI to give 6-iodohexyl pendant groups; condensation with EtO2C-p-C6H4ONa followed by hydrolysis gives the desired rigid-rod polyelectrolytes. Under appropriate reaction conditions all steps occur highly selectively and almost quant.; no degradation of the polymer backbone occurs as verified by high resolution NMR spectroscopy and osmometric investigations. Thus, structurally homogeneous carboxy-containing PP of well-known d.p. are prepared In the experiment, the researchers used many compounds, for example, 1-Bromo-6-methoxyhexane (cas: 50592-87-5Quality Control of 1-Bromo-6-methoxyhexane).
1-Bromo-6-methoxyhexane (cas: 50592-87-5) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Quality Control of 1-Bromo-6-methoxyhexane
