Notes:
Vitamin B1, in chloride (1) or iodide form, decomposes thermally in the mass spectrometer mainly into 2-methyl-4-amino-5-chloromethyl(iodomethyl)-pyrimidine and 4-methyl-5-β-hydroxyethyl-thiazole, and partly, by loss of HCl (HI) under cyclisation, into the base 2. The mass spectrum exhibits peaks due to these products and their fragments. The mass spectra of some model compounds are discussed.
