Abstract

Abstract Benzoate and naphthoate esters of C 5 –C 20 isoprenoid alcohols are excellent derivatives for reversed-phase liquid chromatography. Nonlinear responses of log k ′ to changes in the composition of the mobile phase are observed on Radial PAK C 18 columns. In general, the capacity factors ( k ′) increased with increases in carbon content and decreased with increases in the number of double bonds, branching, and Z double bond content. The large extinction coefficients of the aromatic ester moieties especially the 2-naphthoates, provide high sensitivity for UV detection.
