Vitamin B 1 , 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.
