Synthesis of quaternary heterocyclic salts was written by Winstead, Angela J.;Nyambura, Grace;Matthews, Rachael;Toney, Deveine;Oyaghire, Stanley. And the article was included in Molecules in 2013.Recommanded Product: 1-Ethyl-2,3,3-trimethyl-3H-indol-1-ium-5-sulfonate This article mentions the following:
The microwave synthesis of twenty quaternary ammonium salts, trimethylbenz[e]indolium derivatives I (R = CH3, CH2CH3, (CH2)2CH3, etc.; X = I, Br), quinolinium derivatives II, trimethyl-5-sulfo-3H-indolium derivatives III is described. The syntheses feature comparable yields to conventional synthetic methods reported in the current literature with reduced reaction times and the absence of solvent or minimal solvent. In the experiment, the researchers used many compounds, for example, 1-Ethyl-2,3,3-trimethyl-3H-indol-1-ium-5-sulfonate (cas: 146368-07-2Recommanded Product: 1-Ethyl-2,3,3-trimethyl-3H-indol-1-ium-5-sulfonate).
1-Ethyl-2,3,3-trimethyl-3H-indol-1-ium-5-sulfonate (cas: 146368-07-2) belongs to indole derivatives. Indole produced by Proteus, Pseudomonas, Escherichia and other species was shown to be a growth promoting factor in Arabidopsis thaliana. Moreover, it is known that it controls biofilm formation. However, the role of indole in the cell has not been fully elucidated.Recommanded Product: 1-Ethyl-2,3,3-trimethyl-3H-indol-1-ium-5-sulfonate
