Enantioseparation strategies for sertraline by instrumental and crystallization-based techniques: An important issue in quality control.

Enantiomers of a chiral active pharmaceutical ingredient (API) often exhibit different physicochemical, pharmacokinetic, and biological properties. Therefore, enantioseparation becomes a critical aspect of pharmaceutical development. Sertraline, one of the most widely prescribed antidepressant medications, requires purification from its chiral impurities, and this is recommended and essential for its quality control. This perspective highlights the current established research on the separation and quantification of sertraline's chiral impurities, with a focus on instrumental and crystallization-based techniques.
