The chromatographic behaviour of 14 homopyrimidazole derivatives has been studied on thin layers of silica gel, aluminium oxide and ammonia-saturated silica gel. The relationships between structure and chromatographic behaviour, as well as the most suitable systems for separating the individual derivatives, are discussed on the basis of RF values. The delta RMg values, showing the effect on the polarity, are given for certain functional groups.
