On March 29, 1954, Zima, Otto; von Werder, Fritz published a patent.Category: alcohols-buliding-blocks The title of the patent was Choline derivatives. And the patent contained the following:
The compatibility of compounds ROCH2CH2NR12CH2SMe+X- is improved by oxidation of the thio to the sulfoxide group. To a solution of 30 g. dimethyl(尾-hydroxyethyl)(methylthiomethyl)ammonium chloride in 45 cc. water is added 22 g. 30% aqueous H2O2. The yield of dimethyl(尾-hydroxyethyl)(methylsulfinylmethyl)ammonium chloride is 28 g., m. 96掳, also prepared by oxidation of chloromethyl sulfide with H2O2 and condensation with dimethylaminoethanol. In a similar manner is prepared diethyl(尾-hydroxyethyl)(methylsulfinylmethyl)ammonium chloride, m. 126掳. The experimental process involved the reaction of 2-(Methylamino)ethan-1-ol hydrochloride(cas: 62640-03-3).Category: alcohols-buliding-blocks
2-(Methylamino)ethan-1-ol hydrochloride(cas:62640-03-3) belongs to alcohols. In general, the hydroxyl group makes alcohols polar. Those groups can form hydrogen bonds to one another and to most other compounds. Owing to the presence of the polar OH alcohols are more water-soluble than simple hydrocarbons.
