Bis-dithiophosphonic acids and their 3-hydroxypyridinium and 3-(hydroxymethyl)pyridinium salts were prepared by reaction of Lawesson’s reagent with diethylene glycol, triethylene glycol and bisphenol A. Bis-dithiophosphonic acids reacted with 3-hydroxypyridine and 3-(hydroxymethyl)pyridine at a molar ratio of 1:2 to produce pyridinium salts which showed a high fungicidal activity against Candida albicans. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Quality Control of 2,2′-Oxybis(ethan-1-ol)).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Quality Control of 2,2′-Oxybis(ethan-1-ol)
