- W2388722567 abstract "Objective To establish an HPLC method for the determination of S,S-enantiomer in(1R,2R)-(-)-1,2-cyclohexanediamine.Methods Pre-column derivatization of RE-HPLC was used with m-toluoyl chloride as derivatization reagent and Chiral-AGP(4.0 mm×150 mm) chromatographic column was adopted.The mobile phase was isopropanol-phosphate buffer solution(pH=6.1)(15∶ 85) and the flow rate was 0.7 mL·min-1.The detection wavelength was 214 nm.Results The baseline resolution was achieved between the derivants of S,S-and R,R-enantiomers of 1,2-cyclohexanedia-mine.The limit of quantitation and detectability of S,S-enantiomer were 30.1 ng and 12.4 ng.The linear range of S,S-enantiomer was 0.015~0.09 μg·mL-1,and the average recovery was 98.3%(RSD=9.36%,n=9).Conclusion Pre-column derivatization of RE-HPLC with m-toluoyl chloride as derivatization reagent was suitable for the determination of S,S-enantiomer in(1R,2R)-(-)-1,2-cyclohexanediamine." @default.
