Abstract

A mass spectrometric identification and differentiation of pyrimidin‐4(3H)‐ and ‐4(1H)‐ones was carried out. N‐Substitution at position 1 or 3 made the distinction of the two sets of compounds very easy because of their characteristic fragmentation pathways. Most interesting were the spectra of the N‐unsubstituted derivatives, which illustrated a predominance of the two possible NH tautomers in relation to the 4‐hydroxy structure.
