Taborsky, Robert G. published 《Preparation of 5-hydroxy-4,6-dimethyl-3-pyridinemethanol (4-deoxypyridoxine) by the use of hydrazine》. The research results were published in《Journal of Organic Chemistry》 in 1961.Related Products of 148-51-6 The article conveys some information:
2-Methyl-3-hydroxy-4-methoxymethyl-5-hydroxymethylpyridine-HCl (10 g.) and 50 ml. 95% N2H4 refluxed 18 hrs., most of the N2H4 removed in vacuo, and the residue extracted with 60 ml. refluxing MeOH yielded N2H4.HCl, m. 91-2°. The volume of the filtrate reduced to 20 ml., 15 ml. 11.2% MeOH-HCl added, the precipitate isolated, and 50 ml. Et2O added gave a further precipitate The total yield was 8.1 g. 2-methyl-3-hydroxy-4-methyl-5-hydroxymethylpyridine-HCl (I), m. 273° (decomposition). All conditions and isolation procedures were as above except that instead of the 4-Me ether, 5 g. pyridoxine-HCl and 25 ml. 95% N2H4 were used to give 98% I. The experimental procedure involved many compounds, such as 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride (cas: 148-51-6) .
5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride(cas:148-51-6 Related Products of 148-51-6) is a strong antagonist of vitamin B6. Deoxypyridoxine hydrochloride has been used as an analytical reference standard for the quantification of the analyte in food samples using high performance liquid chromatography.
