HPLC Chiral Separation of Uniconazole Enantiomers on Cyralis AM Column

July 31, 2026

HPLC Chiral Method for Analysis of Uniconazole Enantiomers on Cyralis AM Column by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Uniconazole.

Uniconazole is a plant growth regulator with the chemical formula C15H18ClN3O. As a pesticide, works through inhibiting the production of gibberellins, which are plant growth hormones. It is typically used in perennials and ornamental plants to ensure they are a marketable size before they bloom. You can find detailed UV spectra of Uniconazole 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 Uniconazole 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.

Uniconazole 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 and Ethanol. Detection is performed using UV.

Uv-Vis Spectrum of Uniconazole

If you are looking for optimized HPLC method to analyze Uniconazole check our HPLC Applications library

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 compound was dissolved using acetonitrile.
