Enantioseparation by Thin-Layer Chromatography.

This study focuses on enantioseparation by thin-layer chromatography.. The research employs high-performance liquid chromatography (HPLC) techniques to address analytical challenges in the pharmaceutical field. Both high-performance liquid chromatography (HPLC) and thin-layer chromatography (TLC) techniques should be considered complementary rather than competing, with TLC being used widely in organic synthesis and analytical research. Chiral TLC provides an easy technique for the resolution, isolation, and routine quality control of the enantiomeric purity of active pharmaceutical ingredients... Research Background and Significance Enantioseparation is a crucial analytical process in pharmaceutical research, particularly for the development and quality control of chiral active pharmaceutical ingredients (APIs). The presence of enantiomers often affects the pharmacodynamics, pharmacokinetics, and toxicity profiles of drugs, making their precise identification and quantification imperative. Traditionally, high-performance liquid chromatography (HPLC) has been the gold standard for enantiomeric resolution due to its high sensitivity and reproducibility. However, thin-layer chromatography (TLC) remains a widely used complementary technique, especially in contexts requiring rapid screening, cost-effectiveness, and ease of operation. This study by Bhushan (2026) explores the synergy between TLC and HPLC in pharmaceutical enantioseparation, emphasizing TLC's role in early-stage organic synthesis and routine quality control while validating HPLC methods that enhance analytical reliability. The significance lies in demonstrating how integrating these chromatographic techniques can optimize enantiomeric purity assessment workflows in pharmaceutical laboratories. Experimental Des
