Popis: The first, sensitive, and rapid chiral method was developed for enatioseperations and determination of cabotegravir and its enantiomeric impurities by using HPLC and LC-MS. Cabotegravir is an antiretroviral medication used for the treatment of HIV/AIDS approved by the food and drugs administration (FDA) in the year 2021. The cabotegravir chiral separation was achieved on the coated cellulose-tris (4-chloro-3-methyl phenyl carbamate) (CHIRALCEL OX-3R) column in HILIC mode and the total run time is less than 15 min. The effects of mobile phase composition, elution mode, and percentage of organic modifier as well as the effect of mobile phase-additives and column temperature were investigated on selectivity, resolution, and peak symmetry. The mobile phase consisted of acetonitrile and water with 0.1% (v/v) addition of formic acid additive with the flow rate of 1 mLmin
