The present study is intended to develop the high-performance liquid chromatography (HPLC) method for the analysis of Canagliflozin using the analytical quality by design (AQbD) approach. The key parameters were methodically optimized with the help of factorial experimental design, and contours were plotted when investigated using Design Expert software. A stability-indicating HPLC technique was developed and validated for the quantitative estimation of Canagliflozin, and its stability was assessed using various forced degradation conditions. Successful separation of Canagliflozin was accomplished using a Waters HPLC system with a photo diode array (PDA) detector and Supelcosil C18 column (250 × 4.6 mm, 5 μm) and 0.2% v/v solution of trifluoroacetic acid in water/acetonitrile (80:20% v/v) as the mobile phase maintaining the flow rate at 1.0 mL/min. The detection wavelength was 290 nm, and Canagliflozin got eluted at 6.9 min with a run time of 15 min. Canagliflozin peak purity values in all degradation conditions indicated that the peak is homogeneous, and therefore this method can be considered stability-indicating. The proposed technique was found to be specific, precise (% RSD about 0.66%), linear (12.6–37.9 μg/mL), rugged (overall % RSD about 0.50%), and robust. The standard and sample solutions were stable after 48 h (cumulative % RSD about 0.61%). The developed AQbD-based HPLC method can be used for the assay of Canagliflozin in Canagliflozin tablets of regular production batches and stability samples.
