Chiral separation of 1-(Naphthalene-6-yl)Ethane-1,2-diol
Applications | | KNAUERInstrumentation
Chiral separation plays a crucial role in pharmaceutical and agrochemical industries where the biological activity of enantiomers can differ dramatically. Effective resolution of enantiomeric compounds such as 1-(Naphthalene-6-yl)Ethane-1,2-diol supports drug development, toxicity studies, and quality control by ensuring accurate enantiomeric purity measurements.
The study aimed to develop and validate a robust high-performance liquid chromatography (HPLC) method for baseline separation of the enantiomers of 1-(Naphthalene-6-yl)Ethane-1,2-diol. Parameters such as selectivity, retention, and resolution were optimized under isocratic conditions.
Chromatographic separation was performed on a Eurocel 01 cellulose-based chiral column (5 µm, 250 × 4.6 mm ID). The mobile phase consisted of n-hexane and 2-propanol (90:10 v/v) at a flow rate of 1.0 ml/min, maintained at 25 °C. Sample volume was 10 µl, and UV detection was carried out at 254 nm.
The enantiomers exhibited retention factors k′1 = 7.98 and k′2 = 6.63, yielding a selectivity factor (α) of 1.20. The chromatogram demonstrated clear baseline separation with well-defined peaks. The method showed reproducible retention and selectivity, indicating stable interaction between the analyte and the cellulose-based stationary phase.
Advancements in chiral selectors and sub-2 µm particle technology are expected to further enhance resolution and reduce analysis time. Integration with mass spectrometry detection may offer additional structural insights, while automation and high-throughput platforms will streamline routine enantiomeric screening.
The developed HPLC method provides a reliable, reproducible approach for the chiral separation of 1-(Naphthalene-6-yl)Ethane-1,2-diol, facilitating its application in pharmaceutical research and quality control.
