Title: Evaluation of octanol-water partition coefficients using capillary gas chromatography with cold on-column injection

Journal Article · · Anal. Lett.; (United States)

A general procedure is described for the determination of the octanol-water partition coefficients (log P) of very lipophilic compounds by the shake flask method, employing the analytical technique of capillary gas chromatography with cold on-column injection. The solute and an internal reference with a known log P value are partitioned between the layers of an octanol-water mixture and their relative concentrations are determined by analysis of each phase, using highly standardized chromatographic conditions. The overall method is demonstrated to be convenient, reproducible, and useful for the determination of the partition coefficients of a wide variety of compounds with log P values as high as 5.7. 14 references, 1 figure, 1 table.
