Reverse Phase Chromatographic Method of Analysis for Assay and Content Uniformity Estimation of Drug Substance Sitagliptin, Metformin and Empagliflozin from Available Marketed Formulation
Abstract:A new method of analysis with reverse phase chemistry was designed and developed. Validation for method of analysis was performed for its intended use to calculate assay and content uniformity of drug substance sitagliptin, metformin and empagliflozin in the drug products. The method has a run time of 10 minutes on X-bridge C18 column having 250 mm length, 4.6 mm internal diameter and Particle Size of 5µm, by the use of 0.1% Trifluoroacetic acid Buffer 40%: Methanol 40%: Acetonitrile 20% ratio as constituent c… Show more
