Quality by design-based HPLC assay method development and validation of linagliptin in tablet dosage form. Eur. J. Pharm. Med. Res. 4(02), 486–494 (2017). Preparation of ρDAB (2 × 10 –3mol/l) solution by dissolving 29.8mg in 100mL of methanol with good shaking, was freshly prepared. The effect of prolonged heating time on this reaction was controlled by monitoring the color development at different time intervals (10–60min) at 70–75°C. Maximum absorbance values were gained at 35min (Fig. 3b). Stability of the reaction product
