[High pressure liquid-liquid chromatography: correlation between retention times and biological activity of 1,3,5-triazine derivatives].

An investigation has been made of the possibility of using the retention times t obtained by reversed phase high pressure liquid-liquid chromatography in the study of quantitative structure-activity relatiionships. Taking as an example a group of herbicides which inhibit the Hill reaction, it was found that log t is additive and can be used as the hydrophobic parameter in regression analyses. The characteristics, advantages and possible developments of the method are discussed and the analytical interest is highlighted.
