An HPLC-MS method for simultaneous quantitative determination of a novel gestagenic pharmaceutical and two of its metabolites in rat and rabbit blood sera was developed and validated. The method was selective and specific. The detection limit for all analytes was 5 ng/mL; lower limit of quantitation, 10 ng/mL. Calibration curves for all analytes had the form y = ax + b. The correlation coefficients were >0.99. Matrix effects, degree of extraction, and stability of analytes in standard solutions, analytical samples, and the biomatrix with multiple freeze—thaw cycles were studied.
