HPLC Chiral Separation of Dichlorprop Enantiomers on Cyralis AM Column
August 3, 2026
HPLC Chiral Method for Analysis of Dichlorprop Enantiomers on Cyralis AM Column by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Dichlorprop.
Dichlorprop is a chlorophenoxy herbicide with the chemical formula C9H8Cl2O3. It is used to kill annual and perennial broadleaf weeds. It is widely used within the United States. It works through increasing cell wall plasticity, biosynthesis of proteins, and the production of ethylene which leads to excessive cell division and therefore damage to vascular tissue. It is acutely toxic, but is a severe eye irritant. You can find detailed UV spectra of Dichlorprop and information about its various lambda maxima by visiting the following link.
This application describes a normal-phase chiral HPLC method for the separation of Dichlorprop enantiomers using SIELC’s Cyralis AM chiral column. Cyralis AM is an amylose-based chiral stationary phase (CSP) designed for enantiomeric separations, optical purity testing, chiral impurity analysis, and stereoisomer characterization in pharmaceutical, chemical, agrochemical, and fine chemical applications.
Dichlorprop can be retained and analyzed using the Cyralis AM stationary phase column. The analysis utilizes an isocratic method with a mobile phase consisting of Hexane, IPA, and TFA. Detection is performed using UV.

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

Application Column
Obelisc R
SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.
