Abstract

2-,3-and 4-Hydroxyphenylpyridinium chlorides were prepared for comparing their behaviour under electron-impact. No molecular ion peaks were observed in their spectra and all exercised loss of hydrogen chloride at different rates. The peaks at m/z 171 and m/z 172 were highly abundant in the structure of 2-rather than in the 3-and 4-isomers.
