Characterization of 2-methyl-4-amino-5-(2-methyl-3-furylthiomethyl)pyrimidine from thermal degradation of thiamin
Thiamin hydrochloride was thermally degraded in phosphate buffer (pH 6.5) at 110 °C for 2 h. A major decomposition product was isolated by column chromatography and structurally identified by spectrometric techniques (1H NMR, 13C NMR
