DEVELOPMENT AND VALIDATION OF SPECTROPHOTOMETRIC METHODS FOR THE DETERMINATION AND SPECTROSCOPIC CHARACTERIZATION OF VILDAGLIPTIN USING II -ACCEPTORS IN PHARMACEUTICAL PREPARATIONS
Three simple, quick and sensitive methods are described for the spectrophotometric determination of vildagliptin (VLD) in pharmaceutical preparations. The methods are based on formation of colored charge transfer (CT) complexes between VLD as n-electron donor and chloranilic acid (CA), tetrachloro-1...
