Synthesis of ω-hydroxy quaternary ammonium bolaform surfactants was written by Davey, Tim W.;Hayman, Alan R.. And the article was included in Australian Journal of Chemistry in 1998.Application of 56523-59-2 This article mentions the following:
Several members of a novel class of ω-substituted asym. bolaform surfactants were synthesized to investigate their surfactant and biol. properties. The ω-hydroxy trialkylammonium and pyridinium surfactants have significant antimicrobial and antifungal activity relative to their conventional analogs. For conventional quaternary ammonium alkyl surfactants, increasing the hydrocarbon chain length causes a decrease in the surfactant monomer solubility and a corresponding decrease in the biol. activity. No such trend is observed for the ω-hydroxy quaternary ammonium bromide series. In the experiment, the researchers used many compounds, for example, 15-Bromopentadecanoic acid (cas: 56523-59-2Application of 56523-59-2).
15-Bromopentadecanoic acid (cas: 56523-59-2) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
