The purpose of this study was to separate and develop a sensitive chiral liquid chromatography-tandem mass spectrometry (LC-MS/MS) technique to estimate the (+) and (−) enantiomers of imeglimin in its formulation and validate individual enantiomer of the drug. Imeglimin is used to treat type-2 diabetes (T2D). The chiral stationary phase was reverse phase Chiralpak IG-3 (100 × 4.6 mm, 3 μm), whereas the isocratic mobile phase was methanol and 10 mM ammonium acetate (95:5 v/v ratio) and the flow rate was 0.5 ml/minutes. The resolution of the (+) and (−) enantiomers was monitored using LC-ESI-MS/MS in positive transition at 155.0 m/z (M+H) for imeglimin. The (+) and (−) linearity ranges from 10 to 100 ng/ml. The correlation coefficient (R2) of the (+) and (−) imeglimin enantiomers was found to be linear. The retention time of the (+) and (−) enantiomers of the drug was 2.876 and 4.325 minutes and the total run time of the chromatographic resolution was 5 minutes. As a result, our goal is to separate the enantiomers and develop a fast, sensitive, and cost-effective method for estimating (+) and (−) enantiomers in its formulation.
